I think the clothing toys are fine :) Just make sure there are no buttons or loose strings that the cats can eat...my other cat Milo seems to eat everything D:
Another interesting fact, (I seem to know too much about cats sorry) is that some cats like my Milo can smell a product in plastic. It's called 'tallow' that is made out of rendered animal fat. It is not a very known thing or even scientifically proven; but too many cats seem to eat plastic bags and wrappers. So I would keep a look out for plastic wrappers of any kind that people leave around at the shelter just in case. I hope this has helped!
