I think the only buff it needs is changing the ability cost to 1
to compare with the most similar card, Rustler:
while Rustler can generate quanta by its own, the cat needs to be paired with another card
while the cat can also generate other effects (skeleton, bone wall, etc), Rustler can use its ability multiple times per turn
If this card stays as is then Rustler needs a nerf and I don't think Rustler needs a nerf, just to show how UP this card is in my opinion.
