I'm not sure there is much you can do about the trees or the lizards, other than locking your cat indoors - which is probably not feasable or desirable!
Try not to worry though. Throughout my life, I have known many cats to climb many trees and I have never had one have a problem. It's pretty natural behavior, as is the hunting. As Prettykitty says, there is no one measurement for how high a cat can jump, it depends on agility, weight, age, etc. But cats tend to know their own capabilities pretty well.
Cats will be cats! At least a lizard isn't a bird (I hate all the feathers all over my carpet :)
Margy,
How’s it going?
Cats can jump up to seven times their tail length, seven...........seven. Some kitties will jump less, others a bit more depending on health issues and age! I can’t really tell you an exact length because cats are different.
How do you stop her from bringing on lizards? Good question! lol
