Hello, so I am not a really new guinea pig owner I have had 3 before my young guinea pig I have now who by the way is named remus. I have never had this problem before eith my past 3 female guinea pigs all who I have cared for and given new good homes too all are still healthy as I'm told by there owners, but onto the real problem. A few months ago I went, to petsmart and bought an 8 week old male guinea pig his name is remus, he was smaller then other guinea pigs and still seems to be a small guinea pig, he is only 3 months old now, he has always been healthy very lively and he would always drink his water right up very fast and eat his food up right away as well, I can say I give him fruits and veggies but not a ton of them. Just recently I noticed that remus wasnt drinking or eati g how he usually does usually when I go to change his water most of it is gone but bery recently id come to change his water and itd be completely full. Same with his food, and usually when I open his cage or even during the cage he would usually be running arounf a ton but lately he has also been ditting in his house inside his cage and not moving. So today I decided to take him out for a little while so my nephew could see him but when I set him down I noticed how he would sit was off. It seemed like he would sit more on the backs of his back feet and not sit regularly and I watched as he would walk it seemed hed some what wobble, like he was walking on the back of his back feet as well. I found this very odd so I left him for a few short minutes with my nephew who is old enough to trust with a pet alone so I went to my guinea pigs cage to change it and I took his little house out from the cage and noticed the bedding on the inside of his house seemed to have diarrhea in it! So I asked my friend what should I do and she said to try and get him to drink more water and to eat also to keep him warm so I been having him sit in my lap like he is now and trying to get him to drink and eat but he is having none of it and keeps moving up in my lap and laying someehat on his side. I am getting very alarmed this has never happened before with other guinea pigs for me and I love remus very much, I do not have enough money for a vet and I really dont have any vets that close to where I live and I am very afraid for him please it would be helpful if someone new what I could do for him.thank you
