Well ,i used to had a cat (when i was 10years old) ,he could do one amazing trick when he was young.
We had a tree in our garden ,i don't know the english translation of that tree.I can give you a discription of that tree: it has a sort of dreadlock branch shape ,wich mean's that all his"branche's" start on the top and go toward's the ground.It's like a tree with a lot of cord's attached to the top.
Anyway ,my cat seemed to learned at one point to use these branche's to "swing" with them "tarzan style".He always crawled to the top ,jumped down on one of the branches and used it to swing after bird's.
Afcourse ,that way he never catched anything (with the exception of one crow once) but usualy ended up some feet from the tree.
Still ,it was pretty cool to see my cat jumping down the top of the tree ,swinging down on one of the branche's ,and then fly acroos the garden to land in some flower's.He always managed to land on his four feet though ,and was never injured in this breathtaking stunt.
I saw him taking that craw ,he hit him in mid air with his claws after releasing a branch.it was one of the coolest thing i ever saw (and he made a cool sound while doing it) .I don't know the total though of bird's he killed that way ,cat's usually hunt at night.
He was very succesfull with the ladies of the neighbourhood.when he came older ,he was sometime's gone for a fair amount of day's.Sometiumes 2 days ,then 3 or 4 days.Eventually he never came back.
I cry'd a lot then.I really love animal's ,and losing one was very hard for me.I think that is the reason why my parent's never took a new pet.
