Is 1 hour of floor time neccesary? Because it takes me a while to set u floor time, but my 2 pigs just sit there. They never run or play, only in there cage. So could I just do it once a week? They will chew on the bars to get back in the cage. They have a 2x5 with a 1x3 section coming off of it. So pigloos are in one play, kitchen in another, and they have 2x4 of running/lap space. I understand in a petstore cage, but wiht all that room how come they need more? They hate floortime! And it takes up alot of my time. Please help!
