Hi! there is so much information out there on piggies i couldn't just write it all down.
visit
www.guineapigcages.com
although it is primarily on the C&C cage (a great option!) it has other useful tips and information. As well as a forum. Although you can browse this forum here for some info.
Also look at the photos on that site as they will give you a visual idea of what you're wanting. There are also photos of our cages in the housing section.
As said before, it is good to get two! Though you will need more room if they are males.
you may also see lots of people using fleece blankets. this is a high maintenance bedding and takes a while to get used to. it doesn't always please everybody but i am about to start using fleece so we'll see how it goes. people often seem to ask which is the best bedding but you'll find it comes down to personal opinion as there are always pros and cons.
make sure you have enough space. you'll quickly realise pet store cages are not the right way to go. also, guinea pigs don't really play with toys, but you can get them hideys and tunnels. some do play but it's not really that common.
in my opinion there are people who own guinea pigs and then there are people who
own guinea pigs. basically what i mean is some like them and think they are cute, don't bother to do much research though and just keep them in a itty bitty pet store cage and then there are people who become dedicated. you have to realise there's a whole other world of guinea pig care outside what seems 'conventional'.
hope i helped somewhat!
