Well I am an owner of Siamese cats and I would not have it any other way except for Siamese cats if there were any cats in the household.
YOu got some beautiful Abyssinians and they look sweet!
All I know they are beautiful cats!
If you got the time, space and some $$$ you can make the cats a wonderful home to stay in. As for the males, I would say keep one or keep some separate if they are papered.
