His current cage is too small for another gunia pig ( even him ). So I am planning to upgrade and get another onebgntoc said:It should work, it looks big enough. I would probably put something at the bottom just in case. Also keep in mind guinea pigs should be kept together.
I think it could be done, the sides would be a tad difficult but if you had like a fleece lining at the bottom I think it'll be okay.StarGirl15 said:I dont think you would want that pool as their forever home though. Cleaning it will be really hard.
