Hi MissRibena, We introduced our very elderly albino cat to a straggly scrawny kitten who had lost its mother one very stormy weekend, thinking sure they,ll be great company for each other, and the stray kitten will have a new 'mammy'.
Boy were we wrong.
All hell broke loose.
and these were two females!
It didn't help matters that our cat was a crochety cantakerous territorial upstart. Up til then she had never been challenged, and was queen of all she surveyed.
We persevered, and the ensuing antics of the two cats kept us laughing. To say they eventually became friends would be overstating it a bit. A watching brief would be maintained on the humans to make sure one did not get more favoured than the other. Anyway the kitten grew and became more than a match for the senior resident, and they often had to be seperated when a wrestling match
proved a little too fierceome for the humans more genteel natures.
I would say to try and get a male kitten if possible, introduce very slowly, for short periods at a time to start with. This will give you an idea of how much fur is going to fly if any. Also try and be there yourself in case a referee is needed.
Cats have an innate independance and are very quick to establish a pecking order and are also very territorial as you probably know, but this becomes more fascinating to watch when theres a new kid on the block.
Give both the same food, the kitten will probably be weaned when you get it.
As for giving a cat a bath, not unless you want your eyes scratched out.
No self respecting cat would be caught dead in a bath.
Good luck, btw have a word with your vet as well and ask his/her advice
