Yup... When I was volenteering at a rescue, a huge 20 lb kitty took a chunk outta my arm- It got infected really bad, and i had to go to a urgent care clinic! Cat bites and scratches are definatly not something to take lightly.
I remember about a year ago, before I had my rabbit (which I got in July this year) there was this cat (called willo) who kept coming to my house every day, one day I fed it tuna, ate it, then it got ran over outside my lane, and my dad and me took it to the vets, it had broken its pelvis, so we went round an estate near use, and found the owner, and told her. She thanked us etc. and then this other cat the exact same came in and it was its kitten, anyway, One day my mum saw Willo again and called it over, and i stroked it and it went very aggressive and scratched me deeply, and tryed to bite me so i chased it out and a few months ago outside my land AGAIN! I found one (don't no if it was her or her kitten) dead!
Even though I wasn't very keen on her I did feel sorry for her and the owners.
But now If I see a cat I just make sure it doesn't come near my garage (where my rabbit is kept) in its hutch/run.
by the way... don't worry, we don't keep our car in the garage! and my rabbit doesn't run around in the garage, its hutch and run are in there, it has its hutch inside the run which is 6ft by 4ft so it gets plenty of exercise, but I still bring it in to the kitchen every day or so, can't let it roam free because it would bite the wires and just incase (even though it is litter trained) it would you no what... But the kitchen is vynal floor so...
