I would do as chico stated, take the kitten with you. It's not like they can evict you, you own the place. If they then take you to court, and I doubt they would over a kitty due to legal costs, I would fight it.
Geesh, condo regulations are really infringing on personal rights, it you ask me
.
And from now on, please don't buy from a pet store
, it enables kitty and puppy millers to continue their business
