I have 4 indoor cats, two are ten yrs,, 1 is 4 yrs. and the last is 7. I have to separate the 7 yr. old (she weighs over 20 lbs) from the others as she hates other cats and people The 4 yr. old picks on one the 10 yr. old ( both males). My big problem is the 7 yr. old. I have been feeding 3 feral kitties ( 2 I have tamed, but want to keep 1 of them). I let the 3 ferals inside to feed as it makes my neighbor mad . I live in a mobile home court and she has turned me into the office, I guess it's against the rules. The 7 yr. old smelled the outside kitties and attacked me like a tiger. She xhased me into BR were I holed up for 10 min. I had to take a piece of furniture to get her back into my bedroom. Is there something I can do about the 7 yr. old. The outside kitty I want to keep is an old male, not neutered which I will take care of if I can bring him in without being attacked by the 7 yr bruiser. I would give her away but no one would take her as she's so mean. Thank you for any help.
