It is kinda amazing that not more felines are used. The canine model is just a bit janky with the jawline and cheek slider lol. But besides that, I do think it is down to preference like the others have said. In the furry community wolves, dogs, and foxes are some of the most popular. Lions, tigers, and other big cats are a bit more harder to find. I used to love wolves a lot, now I love aquatic animals, my fursona is a lion...so I mean lol.
