I was reading my previous post and noted I omitted a phrase re the weight of the red tail hawk. I should have said the largest red tail would go no more than four pounds. The average weight would be 2.5 to 3.5 pounds. With the redtail lifting no more than 1/3 of its own weight, any critter close to a pound would not likely be in danger from a redtail. In truth though, any hawk would take a baby rabbit or small kitten if it was readily accessible and the hawk was hungry or had babies to feed. Up on the mountain it was the eagles, coyotes, and owls that plagued the cats and it took a very smart cat to survive. Those who did knew how to keep themselves out of trouble, however.
As for the raccoons, yes, a raccoon will aggressively and competently defend itself if attacked or threatened by a cat and of course will defend its babies if the cat should threaten them, but it has been my experience that raccoons and cats pretty well ignore each other and keep out of each others' way. My daughters's cats and the resident raccoons have always co-existed quite peacefully in California. I think it would be pretty unusual for a Raccoon to hunt or attack a cat that was minding its own business. Raccoons do like catfood but there is no reason to go randomly shooting raccoons.
(Once tired of raccoons coming in through the pet door and raiding her kitchen, daughter installed an electronic pet door activated by a special collar on the cats. It was effective though one of the less adaptable cats never quite got the hang of it and had to be let in and out manually ever after.)
