sure, here's a few
-cat legs have 4 main parts, I attached an image with an example (blue sketch)
-cats come in a lot of variety but something that's consistent with cats is their ears, house cats/domestic cats have pointy ears and wild/big cats have rounded ears. Another thing to note about cat ears is that they're very thin, I included some doodles to show how to draw thin ears since I had trouble with it for a while (green sketch)
-cat skulls are very rounded, cats generally have oval-like skulls, I included 2 references and a shape to explain it better, right is house cat and left is a tiger. Cat skulls are also composed of 2 parts, the noggin shield (top) and the chompy chomps (bottom) and no I don't know the scientific names- the noggin shield has 2 big fangs attached to it and the chompy chomps have 2 other smaller fangs, make sure to include those teeth to really define that it's a cat (pink sketch)
-cat bodies are slinky, made to get around and be flexible, their bodies should reflect that by having a sort of slim torso. I included a small very basic sketch of an anthro cat for clarity if that's any help (red sketch)
if you have any specific questions feel free to ask, I've been doing cats for a while so I'm completely willing to answer any simple questions
