They’re not “King of the Jungle” for nothing.
My sister took in a little stray calico female kitten and she had two full grown labs who had been with her family for at least a decade and that little calico quickly established herself as the queen B of the house smacking the dogs into line and placing herself as top dog. The labs died recently and my sister got a new female lab pup and it behaved as all pups do until the cat imposed her rules.
My sister was on the couch and the cat was sitting next to her and she watched as the pup had a chew toy that would squeak when she bit it across the room. This was going on and on and my sister watched the cats reaction. The cat took note of the squeaks being made by the pup and bored in intently with her eyes, annoyed and perturbed. After a few minutes the cat stood up, jumped to the floor just off the couch and got the pups attention for a second. The pup looked at her and stopped chewing and squeaking for a minute and the cat sat down not moving at all.
The pup then started chewing on the toy again and it was squeaking and the cats tail whipped a couple of times and she walked over and slapped the snot out of the pup on the nose. The pup yelped and ran to my sisters husband and cowered. The cat calmly walked back over to where my sister was sitting on the couch, jumped back up there and did the cat meatloaf sitting pose next to my sister with smug satisfaction. As my sister said the cats reaction was like “I told you to stop bit*h!”
