I had a white cat once, really pretty, but mean as a snake. He had no front claws; we declawed him to keep him from killing my mother’s Maltese dogs. Anyway this cat without claws would bring home full grown rabbits it had killed. He developed a taste for crow chicks. He had no claws but would jump from low branches until it got to the crow’s nest and get its babies. I wouldn't of believed it if I hadn't seen him do it.
Well one day as we watched from the window in the kitchen... in the back yard the crows gathered all around our house..It looked like a scene from the Birds, by Alfred Hitchcock. Sure enough here comes my cat...they waited until he was at the base of the tree...and they all went for him, dive bombing him...LOL I didn't know that cat could move that fast, he made it a hole under the porch or he would have died, they meant business.
After that, I never seen him go for that nest again..Mommy bird had called in all her friends to get that cat, it was a calculated attack..They waited till he was in the middle of our 1 acre lot by that tree so they had the most opportunity to kill him before he reached the safety of the house.
