The sleeping pouch is ALWAYS being cleaned because it stinks so much! I just have a lot of fleece pouches and hammocks for them now, its thicker than the old pouches I had and their nails don't get caught as often as they used to.. I bought one of those wheels that are made just for the suggies and they put "trim traks" in them and it keeps Moofys nails down a little (hes the only one that uses it)
Oh! Coconut sleeping pouches work well too, I have a pouch with a coconut half in it that I bought and they never get caught in it, once all 3 of them squeezed in it and slept there.. I'll get a picture of it for you later tonight.
