My cats definitely think they are yorkies. They race for treats when the babies get some. They eat and sleep where the babies do. The catch is, they play with them sometimes, but they will turn around and swat to show they are the boss. The puppies are sorta terrified of them, yet they can't stop themselves from jumping at them. When the pups are laying all over me and the cat jumps, they get this funny scared look on their faces and stop moving. They wait for her to look away so they can split.
I do think dogs should definitely NOT eat catfood, to rich in oils or something. I let my cat eat the dogfood and keep the catfood up to high. When i spill some, I let the babies have it, like a treat.
