Hello. I just got a male guinea pig a couple of weeks ago. For the past two days he has been sitting in one specific spot of his cage and squeeking. I figured he was hungry so I gave him food but that's not it. When I go up to him he runs and hides then comes back out and goes to that corner. Is he just comfortable there or is he sick?
Please have any new guinea pig health checked as a matter of course unless you adopt from a good rescue with a mandatory quarantine and vet care.
Your little boy's behaviour is likely a mixture of feeling very exposed in his new home and very lonely without having the comfort of a companion, especially if he is still a youngster - imagine sending a toddler child of yours to live on the ship of giant aliens that may or may not be cannibals. As far as shop guinea pigs with minimal human interaction are concerned, we smell and act like predators. Guinea pigs are prey animals that are wired to live in groups; they are not born as living cuddly toys without the company of your own kind. As a human, you simply cannot be around at all hours of the day for the next 5-7 years to fill that social need.
If you can, PLEASE consider a companion and ideally date him at a good rescue, so you can enjoy the delights of two personality matched piggies. It is going to bring out your boy much more quickly. How old is he?
Please be aware that bonding piggies is not as straight forward as sticking another piggy into the cage - that can be a recipe for disaster. Key to any successful piggy bond is character compatibility and mutual liking. A good rescue will consider this; you are also only adopting a healthy pet and only if there has been success with the bonding, so there is minimal risk for you but maximal profit for a little extra effort!
Please take the time to read the guides in this link here. You will find it most helpful.
One section is dedicated to making friends with your piggy by avoiding predatory behaviours and by using guinea pig behaviours to make meaningful contact in ways that he instinctively understands.
Another explains about companionship and guinea pig behaviours, as well as learning about spotting early signs of illness and what is normal in a body and what not.
It also contains links to recommended good standard rescues we can guarantee you are in safe hands (sadly there is no licensing or control of rescues or breeders in English speaking countries) as well as recommended vets in several countries.
