I simply feel so sad for this poor cat living out his life in a bathroom (the fact that it is a bathroom next to a kitchen doesn't mean a lot). It's no life for a cat, sitting in their all day, mostly alone and having to wet and dirty in a pair of kitty pants

This poor boy seems to serve no purpose other than to periodically impregnate your queens, what an existance for any animal. The poor cat must be slowly going crazy in that bathroom, my heart breaks for him

Please give some real thought to his welfare and if you can't provide him with the life he needs and deserves, do the right thing, neuter him and try and find him a good home.
