When I use a towel, I use a really big one, and fold it over in my mega cat carrier and change it twice a day, but when I change it, I don't change it out. I take it outside and shake it off, and then fold it over to a clean spot. And the kitty carrier it like a foot and a quarter long, and about a foot and four inches wide. It stands taller, but its big enough to hold her in full grown (which I am not going to do). But when I use a towel, which is all I have, I shake it all the way off and then fold it over, and I get three uses out of it, I guess. And put it in the washing machine after like three uses. And just get a new one! 
Thanks for all the tips
