Is this just time outside of the cage in a different enviroment? Right now we put our piggies in a gigantic pool with some towels and fresh veggies and hay and they run around or crawl in our laps (we can fit in the pool). I see a lot of people actually let them run around the house. Is this in a small room? Our entire top floor is an open floor plan so they could get into way much trouble or get lost. We also have cats were are still getting to know them. There also enlies my other issue. PEE. Poos, fine, I can vacuum those up...but pee? Doesn't floor time equal pee in the carpet? I have already found my cats jumping in the pool if I don't put it away and peeing were the guinea pigs went and they NEVER go outside of their littler box. They must smell that smell and think it's okay for them to go there too. I don't need cat pee (or guinea pig pee)in my new house. What is your floor time like? Also, the guinea pigs only use their litter box for pee in their cage. Would they do the same outside of the cage?
