I absolutely adore cats and have one of my own. My cat is very gentle and domesticated, and she has not fought with another cat in the house previously. My cat is neutered and has no conditions (no fleas etc; I give monthly flea treatment). I do not have a litter box as my cat is used to just going into the garden, but for a small cost I am willing to buy a litter box and litter for your (litter trained) cat to use.
