My Guinea pig keeps getting no super soft poos, just one of them, she has been to vet, nothing obviously wrong, she is having a ovarian scan just in case, but vet said try probiotics as she gets diarrhoea from almost any veg. I have read about different probiotics got confused and just bought protum Probiotic paste. Has anyone tried this on guineampigs. One product pro-c professional probiotic powder appears to be mainly sugar (dextrose) ? I don’t see how sugar is going to cure a tummy problem.
 
Can you do poo soup from her healthy companion? Did wonders for my boy.
 
How do you know which poos are the ones they eat?

It has now been proven that they do not produce a different type of poop to eat. They only produce the waste poop that you see in the cage and eat normal waste poop.

The guide below explains

Wiebke's Guide to Poops

You need to put the companion in a box, feed him/her some snacks and wait for poop. The moment you see poop, put them in water and soak them for a few minutes. Discard the poops then syringe the water to your poorly piggy.

You can give a commercial probiotic as well as poop soup.
Commonly used probiotics are Fibreplex and pro c

Have you removed veg from her diet?

I’ve also added the tummy trouble guide below

Thanks guys will try the poop soup and have bought the Fibreplex as it is such an ongoing softnpoo situation. She went to vet today after having basically cowpats yesterday, vet says she is healthy tummy counts good etc it is definitely her not her cagemate with the grotty poos, she has been off veg for 24 hr. We take them off veg it clears up, restart veg even in small amounts and within a few days she has started again. Yet it is all veg they are used to all carefully weighed as per your food page. So maybe she has gut micro biome imbalance which the veg makes worse, will def try the poop soup. Thanks
 
She probably won't eat it.

I mashed up a fresh poop in water and syringed it to my boy every day for two weeks and his poo was perfect.

I tried feeding it to him in critical care in a dish and he wouldn't eat it.
 
It may be one particular veg she has a problem with. I would reintroduce veg slowly one thing at a time to test her out. My Timmy can't eat coriander.
 
I tend to waffle so I will write this inbullet points and hope my brain a make it make sense. It is an ongoing problem hence writing on this thread. I think it actually pertains to a couple of different threads but I will do my best here.

* Button, big black piggie, you called her stress reactive/agressive something like that

button has a cagemate (small female)
  • button and cagemate did have husband who passed away
  • bought little boy put in next door cage until castrated. This started all the problems.
  • A month later buttons poo got very soft a squishy
  • tried poop soup from the male (she was so interested in him that I thought she would accept it better and he actually pooed on me whereas her case mate didn’t) only did it once as she despised it which I now know is because she despised him and wasn’t in fact enamoured with him as I thought
  • bought Fibreplex. Button Hated it had to put it between slices of cucumber to get her to swallow. Did not seem to help.

* she’s always been a little bit boisterous and aggressive and with the soft poos and a very big extra fat/swollen bum. I suspected cysts. We asked the vet one of the newer exotic vet suggested doing the scan to be sure and she came up clear.

  • failed bonding with male (she attacked him)
  • next two days she spent attacking him through the bars of their cakes and her poos became disastrously soft. You suggested separating their cages which we did and her poops went back to normal without stopping any veg.

* when her sister came into heat and started mounting her her poos got soft then but again waited 24 hours and they were back to normal. I did not want to stress her further by stopping veg. I had decided if after 24 hours it was still as bad. I would then stop the veg and this continued for some time every time the poop’s got back to normal without intervention.



*We have showed her normal poos to the vet which is slightly pointed and the vet said they were fine.

*Another time we showed her quite bad poo (not her worst) and they said” that’s fine if it’s only when she’s stressed.”

*her poos go soft every time her sister stresses her like mounting etc when she’s in heat or even just arguing on a day she feels like arguing (but they do get on really well and like each other, I dont think separating them is a good plan they would miss each other)

  • our dog died I sept and a puppy came which was very hard on my illness, thankfully button seemed fine for the next few months other than occasional soft poo which sorted themselves out without withholding veg

  • dec her poos became very soft, did not clear up so we withheld veg for about a week. Once cleared up we slowly we introduced pepper in slowly increasing amount and her poo is fine then we increased to small bits of lettuce with it as well and her poo was fine then one day suddenly they were bad again with no alteration of what they are eating. Poor button hasn’t had cucumber since the end of November now which she misses.

  • we did the withholding again and slowly re-introducing pepper which was fine and then got soft again for no reason.

*we then had Christmas, I said to mum if this is still a problem in jan we need to see a vet and get advice from Guinea pig forum

  • our sick cat had to be put down beginning of jan, I didn’t think it would affect me too much because although I liked her, she really didn’t like me. But I think with all the other death recently it really threw me I was incredibly depressed and I’ve had two weeks of tremoring.

  • I have finally got the energy together today to write this. It’s taken me the entire day hence why is now so late and I’m in agony.

  • I know none of this is really your guys problems but I just want some advice. The vet each time we have taken her seems to think she’s healthy. Her coat is beautiful and glossy and thick really really is very beautiful. White is most of the time okay it does fluctuate it goes from about 1080 to about 1160.

  • We have her booked in for next Monday, which is when the really good exotic vet is next in. Has anyone had any sort of experience with this? I can only assume extreme stress digestion related problems?


What can I try doing to help? Is there any test the vet can actually do?



Long time ago,(before the boy and button met) I tried to be poop soup but I used the boy poop and obviously she hated it. I’ve been very nervous of trying her sister‘s poop because I don’t want her to decide to hate her sister who is obviously the only pig that I and you guys have said she’ll probably ever be able to live with.


One question can a guinea pig live without vegetables? seems very boring. And quite sad because they enjoy when I wrap up their little bit of vegetable for foraging.



I am very exhausted now and a lot of pain. Anyone has any suggestions that would be great. But is such a lovely pig when you cuddle her she seems to nestled down and go “oh I don’t have to be a boss pig anymore.” i’m sorry for any errors in this. I’ve done speech to text for most of it.
 
I’m sorry to hear you’re still having issues with her

First, the fact you used poop from a male piggy does not matter.
You can using her female cage mates poops - it will not make her dislike her cagemate.
Getting them to take poop soup can be tricky anyway as not all will like the taste of it - its nothing to do with whether they like the actual piggy the poops came from.
Can you tell us how you were administering the poop soup - ie you weren’t trying to feed her the poops? You need to soak the poops in water and then throw the poops away and then syringe the water to her.

You will need to syringe the fibreplex directly into her mouth or try a different probiotic (you can try pro-c), and then immediately follow it up with something nice tasting
Piggies have a huge amount more tastebuds ao trying to disguise something they don’t like the taste of by putting it in food usually won’t work - they will be able to spot the taste of the thing they don’t like incredibly easily.

How old is she?

Can you tell us more about her diet -
How much veg does she get each day?

Her weight is swinging by 80g - how often are you weighing her?
 
Ok it was some time ago,but we put the poops I some water, mashed a little as someone on here suggested and syringe fed, she went ballistic. She also went ballistic when we syringes the Fibreplex into her mouth and spat it all out each time hence resorting to spreading it on cucumber. It did not seem to help at all anyway, just made her put on weight (large amount of fat in Fibreplex).

She is about 1 year and 3 months old. She has not had much veg in the last two months and still getting soft poos and sometimes cow pats. Normally they have a slice of cucumber, some pepper cut up and hidden, a lettuce leaf each and a very small price of celery cut up and hidden. They were having coriander but I stopped that ages ago as it was a new veg and her soft poos had started up and have yet to go away.

The other pigs have 2 pea flakes each most days button does not as again I had found they can be bad for pigs with runny poo. Between the 4 they get through 10 kg box Timothy hay per month plus about a 1/3 so 3 kg of orchard hay. They have 1 tbsp nuggets per pig hidden in hay pile.

I will attach screenshots of her weight changes in a min. I really think it is a stress related poo problem but I don’t know how to help other than stop veg. Cos her sister will stand up to her once I a while which seems to start the stress and soft poos.
 
Most recent weight changes (I have attached all three photos so you can see her weight does go quite down and then go back up regularly)

Sorry I forgot they have a pinch of forage in their hay pile in morning. And because button has not been having cucumber, I have been giving her about a centimetre of a really hard compressed Timothy hay stick which seems to like. I can feed it to her like I hand feed the cucumber to the other so she doesn’t feel left out.
 
Fibreplex will not make a guinea pig put on weight. It’s a probiotic to help repopulate the gut bacteria - it categorically does not directly cause weight gain. The only way you will see weight gain is completely indirectly in that it helps settle the gut so a piggy will then eat more hay but it has nothing to with Fibreplex being fattening at all.
Try pro-c and see if that helps.
(Weight gain happens through eating a good amount of hay. Unhealthy weight gain can happen if they are fed improperly ie being given too many pellets for example.)

So were some bits of mashed poop going into the syringe at all? As I say, you just needed to put the fresh poops in water, let it soak and then syringe just to water to her.

So looking at the weight chart - Her weight does seem to jump around a bit but looking at her last three dates, she is within 50g so in itself not concerning.

If removing veg isn’t helping, it would be worth her being seen by a vet again
 
We are definitely seeing a vet on Monday. But they have not really thought there was a problem with her. Which is why I wanted to check and see if anyone had any ideas that mum could talk To the vet about. Incase they just shrug us off again saying she is healthy and fine.
 
And how often a She be taken off veg? If she ends up only having veg a few days a week because she is clearing up poos for a few days every week for ever, is that going to be a problem? It sounds miserable, but I am more concerned over vitamins etc
 
You can ask for her poop to be tested to make sure her gut is completely healthy.
The other thing that can cause soft poops is pain around the back and but not gut related. She is young so things like arthritis aren’t likely to be a reason but it could be worth getting the vet to check.

If both those can be ruled out and it definitely does come down to stress then there probably isn’t much you can do. If the are closely bonded then separating her from a friend may not help.
If not giving her veg doesn’t help improve anything meaning the issue isn’t a gut imbalance then she may be better off to just be given a small amount of veg anyway. Maybe don’t give her a full cup full, pick something like herbs to give as they contain nutrients but are easier on digestion.
 
Ok I will get all those things talked about with vet, and we will try doingpoop soup from healthy piggie over weekend (mum is on respite from caring for me until Thursday). The girls are definitely well bonded. Button Iicks her sisters ears, they Wheek extra loud if you cuddle both together-until they start a jealous argument.
 
Guinea pig that has been having super soft poos for a long time I have given fibre Plex to for the past three weeks and her poos were a good deal better she was able to tolerate red pepper every day. The fibre Plex has now run out. I had two tubes. I was giving it once a day she absolutely despise it. It’s been two days and her poops are very soft squishy and everywhere again. Do I just continue giving her fibre Plex for the rest of her life or if I take her to a vet is there something they can do to cure her but will they just tell me to give her Fibreplex thanks

If removing veg from the diet and giving a probiotic hasn’t worked (for a mild digestive upset then it usually resolves within a couple of days) then yes she does need to see a vet.
It may be that her gut can’t tolerate veg/certain veg.
Have you tried live microbiome transfer/poop soup - made by soaking just produced poops of a healthy companion in water, and then syringing the water to your poorly piggy
