Congratulations, Cuddlebear, on being POTD! You are ADORABLE! (We cavies!) We're glad you have Zane as a friend but GPs (cavies) do NOT have to have a cage friend. We've adopted GPs for over 30 years (from the Humane Society) and many, many GPs do NOT like sharing their cage and food and toys with anyone! Best wishes to you and Zane for long, happy, healthy, fun, safe lives! P.S. Don't forget daily Vit C to avoid scurvy! http://www.guineapigsrfun.net
