I wouldn't feed either a dog or a cat to a snake but if I did i can see that it would be harder to feed a dog because dogs are mans best friend and are much more loving and dont just love anyone like cats!
Not true, my cats have bonded with individual family members. My cat follows me around like a dog and when she wants attention she looks at me and meows or if she wants to come into my room she meows at the door and waits for me to open it, jumps up on my bed and sleeps.
Back when I was young I had a burmese that I had an extra special bond with, a much stronger connection than any dog I've bonded with, and trust me there's been some really special dogs in my life but none of them can ever compare to my burmese.
I think the main reason cats aren't seen as friendly, loving pets is because people don't give them a chance. Dogs bond so easily but cats, you have to earn a cat's trust and friendship and you're guaranteed a best friend for life.
