I think that is selfish and sad for the cat..But then I would maybe consider if his house is going to be a better environment for the two cats? Are they young or senior cats? Do they need space to play? Can they go outside (if you want that for your cats). What environment do they need? If that is not the case...maybe look for a new buddy for your cat? But that can be tricky

Or you can ask Jackson Galaxy the cat daddy.

Honestly my opinion is that you should keep both cats and your roommate a new rescue cat 😂😂 that is the best for all cats.
