I buy my fleece at walmart,it's just as good/safe as any fabric stores.
Sounds like you may be able to litter train,just put the litter box in the corner and seed it with a few poops. I use Yesterdays News unscented cat litter in all my litter boxes.
I got him a litter pan, seeded it with poops, put him on a liner and went to bed. Whe I woke up this morning he had peed and pooped all over his flying saucer. There's a nice spray mark where the waste flung of the wheel onto the liner. :lol: Well not really.
