Advice from Experience: How long does it take an old house cat to deal with a new kitten? [View all]
The history of my old cat, 17 years old, we guess, and a long time loner in our house is told here: My "eating the cat" story.
She has, since being "rescued" from her previous home, never been around other animals, only people. (The problem at my Sister-in-law's home was not just the dog she got, but a bullying cat that lived with her before the divorce that led her here.)
My son just rescued a feral kitten living behind his ex-girlfriend's house.
It's not going well. The old cat is clearly upset by the energetic, bouncy, high energy kitten, hissing and growling, and then going to another room. (We have the kitten in an enclosure for parts of the day.)
I've never had a cat in my adult life who's lived this long, since most of my previous cats (I had only a few) were outdoor types, and didn't make it all that long before being killed in one way or another, usually cars.
Does anyone have helpful experience; will she, the old cat, get over it and become tolerant?
