All pets have (I believe) a single idle animation that they cycle through every 10 or so seconds. Thats boring. Pets should have more idle animations (6-15 per pet), and the usage of those idle animations should be more randomly distributed (not all happening with a set amount of time between them and the last one).
Its not hard to implement and would vastly improve hive pets.
I know it may seem crazy but the lack of detail put into these pets (idle animations + none of them can walk) make pets to me not worth getting. If the cat pet walked on the ground, did lots of cat-related things (scratch its ear, lick its paw, meow (u dont need volume), blink slowly, lash its tail, etc), and could ride mounts with u (u get on ur reindeer and it jumps on behind u or smth) I would buy one today.
