hello and welcome
you really need a muuuuch bigger cage than that! i went with one that size at first, and i quickly learned that it was much to small. C&C cages are the most recomended, because you can expand them, and you can put up a barrior if necessary. you can look at the housing section for examples, or go here for a good website that explains better than i can about the importance of lots of room: guineapigcages.com
you should definitely buy a hidey house for them, the "pigloos" seem pretty popular (they are with my pigs!) because it makes them feel safe. you can buy toys, just make sure they're safe (my brilliant boy roger got his head stuck in a chew log thing, which resulted in a very stressful morning!) but it also seems like cheap things like brown paper bags or kleenex boxes seems more fun to them.
make sure you get a good pellet that is made of timothy hay and has a stabilized source of vitamin C, pigs cant make or store their own. commercial treats are not as good for them, but fresh vegetables (and occasionally fruits) make wonderful treats. Their diet should be 80% hay, alfalfa for young pigs, otherwise go with timothy hay. the rest can consist of veggies and fruits.
the most popular commercial bedding is something like carefresh, wood chips are a no-no because they can cause lung problems. i use towels and newspaper, they seem to like it better, and other people use fleece (better for urine absorption). good website for the care of guinea pigs is guinealynx.com
hope i helped
Thank you for the great reply. I had a look at the C&C cages but as I am in the UK it's quite hard to get the stuff here for them. I'm actually in Scotland and have no Wickes - only B&Q and I have been checking stock for a while at 4 local stores and no sign of the grids for a while so that's why I looked at the already made cages. I will keep checking though even when I have a cage as it will be my goal to get them into one.
I had a look at the pigloos - they look really good - I will make sure to get a couple of them thanks! By chew log do you mean this?

I've seen some pics of some hiding in paper bags - cute!
With regards to food then a bowl (or two?) a day of pellets and a bowl (or two?) a day of veg with a little fruit is what I should be feeding them? Along with a handful or so of timothy (or alfalfa if babies) each day? Plenty of fresh water too. Is feeding them from the same bowls ok? I mean will they share ok or is that just Dependant on their personalities?
I've read about the dust being bad for their lungs. I seen megazorb but not sure if there's anywhere local selling that - I will have a look. I've seen people say megazorb and hay - do they mean timothy hay in with the bedding or another hay for bedding? What do you have to put in their hidey places or just leave that clear?
Sorry for the loads of questions again!
120cm is perfectly fine for two guinea pigs but if you wanted more you'd need a bigger cage.

See here for cage recommendations
Guinea pigs love places to hide so plenty of hiding spots - you can use tunnels, cardboard boxes, plastic pigloos etc
I prefer hayracks as mine just tend to urinate on the hay and waste alot so both my cages have hayracks and they love using them and it helps keep their cage looking cleaner.
Bedding wise avoid sawdust and shavings as they can be quite dusty. Some people use just newspaper and loads of hay and thats perfectly fine but you would need to clean them out more often. I use a bedding called Megazorb which is very absorbant and dust free. You can also use bedding such as auboise or even fleece!
Guinea pigs cannot manufacture Vitamin C so its vital they get it or they can develop scurvy.
Vitamin C is found in fruit and veg and guinea pigs love things such as carrot, cucumber, peppers, coriander, romaine lettuce, celery, plum etc

See here for advice on the low to high calcium rates in foods
Commercial feed wise, there are loads. Gerty guinea pig, wagg crunch etc as make them selective but I have mine on gerty and they eat it all. You can also get your pellet feeds such as science selective and excel.
Thank you for replying! Lots of info!
It would only be the two yes that we get. (for now!)
The pigloos look good - going to definitely get a couple of them.
Ah thanks for letting me know about the hayracks. I think I will keep it in and let them try it out and just see if they are ok with it then.
I like the idea of the megazorb but not sure if I can get it around here - I'm going to have to have a look about and see. Where do you find yours? Is it just enough to cover the bottom I need or a thick layer etc?
Thanks for that link for the foods - I will go and check that out!
I believe the OP is in the UK, and the grids to make C&C cages can be quite difficult to get hold of here. A lot of us have to use commercial cages because of this.
The two mentioned are suitable for two piggies, and comply with the RSPCA guidelines.
Yeah I'm in the UK - Scotland. I've been looking for the grids at our B&Q's but never in stock. I will keep looking though even after I get cage as I may get lucky with it.
Thank you for your reply! Good to know they comply with the RSPCA guidelines.
Hi Lauz, and welcome!
Good on you for researching before getting any piggies.
When it comes to piggies and space, bigger is better, so I would advise you to get the biggest cage you can afford and find the space for.
Does not matter if its handmade, C&C grids or a commercial cage.
I have the second cage you are interested (1.2m x 50cm) in for my 2 boys and they are happy in there. If I had the space, I would go bigger and maybe build a custom made cage to fit in the lounge, but the one we have is good.
I have however noticed that they get frustrated if they do not get floor time and are cooped up in there for long periods of time.
Hope that helps
Aw thank you!
I can get the first cage on zooplus for about £45. The other one is a bit more. The next size up - the 140 - is a huge jump in price and a bit more than I was expecting to pay. I think I will go with the 120 (first one) and aim for the C&C or if I still have no luck then the 140.
I will be getting a little run for some floor time for them too. I've got a space lined up for that. Thanks.
Thank you for your reply!
I have to say i love my c and c trying to find the cubes although hard work was deffo worth it. If you wanted c and c you could try wicks I know they say out of stock on there home page but i called and they had 1 packet. Nettos was selliing them really cheap. My girls and I love my c and c.
Thank you for replying.
I've been having trouble getting the grids in stock at several B&Q's but I'm going to keep trying. Just don't know how long I would have to wait really so going to get a ready made cage in the meantime and keep checking B&Q.
I'd never heard of NETTO'S - just checked online and the nearest one to me is Carlisle - 93 miles away! hehe! Thank you though for letting me know!
hiya, welcome to the forum!

Well done on researching first. As long as you have a 4ft x 2ft cage, it will be fine for a pair of piggies.

|) Don't forget about a pen or run as well. Piggies need floor time.
Thank you!
I'm going to get a little run too - already got a space lined up for that too.
Thanks for the reply!
