Maybe you could stand it on breeze blocks
I have 3 fosters, they have been here nearly a year tho
they were ill as little un's and nobody is interested now other than those on very busy roads, typical! They were feral kittens, they aren't evil just flighty & very nervous of strangers. One has bladder probs so i think il be keeping him, hee hee
Maybe the parents will break on the other 2, they fit in nicely....
