Hi and welcome to the forum

i'm from OZ (aka Australia) you'll love this forum, heaps of lovely people to chat too, and so much info at the tip of your fingers to access!
It could definitely be a good idea for a check up, the vets could listen into his chest and confirm no infections or anything

WOW 6 is a fab age, you must've been doing everything right for this little guy.
I found that when piggies get older they do tend to sit around more and yeah in their wees and poops, not nice i know, but just make sure you do spot cleans thru the day and a nice change of the area he loves to sit around in daily! Piggies do loose weight when they age, they don't move around as much and don't eat as much.
Sorry can't help you on the squeaking other than as i said get vets to check out his little chest

Good luck xxxxxxxxxxxxx
Thank you very much!
I think a lot of it is just a stress free life, he spends a lot of time being cuddled and loved so he's pretty chilled out around people so he doesn't stress out if someone new comes around. Though I have been really lucky with him I've only had to take him to the vet for ringworm(which, he had from the damnable pet shop*shakes fist at it* and they offered to "take him off our hands" grrrr) and for his tooth, which keeps breaking for some unknown reason recently, the vet has no idea whats up with it. But I think I'll see if I can get him in for Monday just to be sure about this.
As a further note it does go away when he coughs and he only has to cough once and it takes a day or so to come back.
Alright, time I employed a good trowel and bucket then to keep him out of his wee, daft thing, ahh well I guess it happens to all of us when we get old.
sorry i cant help with the squeeking although i personally believe a guinea pig should never go without a mate and i think he should have a mate all the time visits arent always enough for such a social little animal mabey try a rescue you could get one close to his age?also its never a good idea to hesitate going to the vet after all our little babys are worth every penny keep us all update would like to know how it all go's

goodluck with your little guyxx>>>
if you want to try avoid more weight loss i wouldnt give him to much lettuce
Hmm, well, I can TRY and persuade my parents but as yet they've said no more guinea pigs so I doubt any more pestering will help, even if I pointed out he needs a friend. But then he did fight with his last friend I think mostly he misses having someone else to watch his back when he's out side munching on the lawn.
Isn't just lettuce, every feed I give him two lettuce leaves, one good chunk of cucumber, celery leaves and some hay in the morning and evening feeds, also he's always got hard food and I keep that fresh and filled, occasionally when we have it in the house I'll give him a bit of broccoli or carrot. For treats he sometimes gets a bit of banana or a cashew nut, he gets two grapes when we have them, he wont eat more than that and when ever we have apples we give him the core. Also he gets to go outside in the grass when ever its sunny and warm or, failing that I bring him in a big pile of it. So it isn't a very restricted diet, also gets apple wood and if he's sneaky he steals silver birch twigs off the lawn.
Hi, when you say you are going to introduce him to your sisters pigs make sure you are very careful. Is he neutered? If you are going to introduce him to girls and he is not then you really need to think of the consequences and if you are introducing him to boys then you need to consider the balance. Boys take a while to bond and introducing an older boy to the pack may upset the balance. Tha boys may not get on with him - and they may stop getting on with each other too....
Regarding his weight, we lost our boar Del Boy a few weeks ago aged 6 and a half and as he aged he also lost weight. He was perfectly healthy just getting on a bit and I guess like humans as they age and become less active they have less muscle and therefore weigh less.
Hope you can find a way of cheering him up soon
They're both boys, both neutered boys in an attempt to stop them fighting as they're utterly nuts at each other, I've introduced him a couple of times and, as yet, it hasn't been a good reception as one gets aggressive and the other tries to mount him(well tries to mount anything piggy shaped in sight) but he hasn't met them now they've been neutered, so I don't know if the dynamics might have changed enough to let him at least eat outside with them as that seems to be when piggies are least aggressive. As her pigs don't get on well as it is I can't imagine he would make it worse really, but it will be done carefully as I don't want everything to be mucked up with them so they have to be split up like my piggy and his buddy(I think they were still buddies really, they just didn't like sleeping in the same cage together)
I feel a bit more at rest about his dropping weight, it seems to have settled now so I think he's as flabby as he's going to get. It's so different holding my sisters guinea pigs, they're all muscle and Jack(my piggy) is just, so squashy by comparison!
