I see. what about a bird then? - if your cats are OK with that.
Parrot species if you have a very strict, takes-no-rubbish type of personality like me. if not, you shall be the parrots pet :lol:
(be prepared to shed out several hundred (or in my case several thousand) for thing like toys, massive cage, toys, vitamins, wormer, cleaners, toys, and more toys, ear plugs... that sort of stuff).
or maybe a blue tongue lizard? bearded dragon, newts? (newt setups can be very beautiful if you are artistic).
