Hi halfpinay515!
I think it great that you are taking so much time to make the right decision. The two Bengals that we rehomed with us were an ex- breeding queen/ tom who reportedly just didn't "take" to breeding but did bond with each other. They had spent 6 months or so in another home after leaving the breeder before arriving with us. I tracked down the breeder who has been fab about sharing info (and was understandably initially concerned that they had been rehomed without her knowledge) so I now have as full a history as I can about them both.
Although I had had (many) moggies for 30 yrs (all from kittens) these cats have been like no other cat I have ever had living with me. They are smarter, faster and more athletic for a start! That said they have blossomed into the most fabulous companions as they settled in and adjusted to the change.
We decided after talking with the breeder that we would not let them be outdoor cats unlike all our previous cats so built the enclosure. We have to juggle the needs of our resident 12 year old cat who does go out but have managed to do so without too much disruption but we are a cat orientated household so their needs dominate.
Having seen the positive changes in them since they arrived has been the most rewarding experiences ever and Malcolm in particular has become the most affectionate and human orientated cat ever.. his "wife" is a little more self contained but comes running for a fuss when she hears Malcolm being fussed over!
Which ever option (adult/ kitten) you go for I am sure it will be great but wanted to share my positive experience of having ex breeding cats coming into our household...
