We adopted cats who were 7 and 8 months old respectively, and we have never been sorry. They are very attached to us, although it took just a bit longer for them to become deeply attached than it might have if they had been infants. They also did well with each other, too. They had been housed in cages next to one another in the shelter, so they already knew one another in advance of being adopted. They were also well trained to cleanliness, which was a plus. We have adopted infant kittens in the past, too, and of course they are darling - but they require a certain amount of work and attention that our older kittens did not. I would certainly not recommend against opening your home to an older kitten - they are still growing youngsters, even if they are living in bigger bodies!
