An angry or berserk cat is a force to be reckoned with! I had one who had fits of rage due to brain damage; he sent my mom to the ER to have her wrist sewn back together and pumped full of antibiotics, nearly blinded me and gave a series of wounds that left one leg stiff and tender for 6 months.
Yes, we had to put him to sleep. Trying to deal with a cat in killer mode is going to be a painful, messy affair.
A trained guard/protection cat is an interesting idea...
Tell me about it. I clip my cats’ claws myself. A very few times I clipped a bit too much and they bled... and the cats remember it years later and go almost crazy when I approach that nail now. Hiss, bite, scratch. How does a cat manage to sharpen its REAR claws? I’ve never watched that in action but my tomcat Timmy does just that. Needles in back and he won’t let me touch them without the worst fight.
