Seeing as pets are available for anybody on every other hotel i think this is a bad idea. Users use animals for ROTW and TRP or RP hotels. Maybe make a limit on how many animals can be in the room per user or just room. It's a bit better then to have to move the whole pet cata to the ultra VIP+ cata. We'll just lose 100s of more users. :P
Some people don't have money / will refuse to pay for VIP. so it's best if it stays as is.
