For starters, my cat is not very good. I could upload a better one that is hand drawn, if you'd like.

Anyway, The first thing about cats is that they have short necks. So their head will be closer to their body than a dog's or horse's.
Second, the forelegs of the cat sort of jut out before curving back for the "elbow". You'll see shape for the hips and occasionally the shoulders.
Cats walk and stand on their toes, unlike dogs, who stand and walk on their whole foot.
Cat faces are sort of squished together, meaning that the eyes, mouth, and nose will all be rather close to each other, again, unlike dogs or horses.
Lastly, cats that have long hair don't have pointy tails. The long, thin fur on the ends of their tails will droop down. If you have a short-haired cat, you will see a sort of "point" at the end of the tail.

Hope this helps!
