I agree with the others. Cat trees are a must with bengals as well as interactive toys. I would strongly suggest Da Bird made by go cats as well as neko flies. If you get the neko flies I wouldn't worry about getting one of their rods because they suck lol. The attachments are really nice and work great with da bird rods. Ebay is great for cat trees and they are very affordable on there. When looking for one make sure it has a wide base. I made the mistake in the beginning and bought a tall slider one. It was fine for BB when she was a kitten but once she got to be 10+ pounds it was dangerous.
Like recommended before make sure you keep him on the same diet as she has him on. If you would like to change it (most people do) do so gradually and after he has been home for a few weeks. I feed mine wet food twice a day and free feed dry. They are both on Innova Evo turkey and chicken dry and a variety of wet foods. Their favorite is earthbound holistic and wellness core. But like all cats yours will be different so it may take you awhile to find some he goes crazy for. I would try to find several over a period of time that he likes because they are known to suddenly hate their once favorite food.
Introducing them should be done as slow as possible. Use your own judgement to see when you think they will be ready. Don't expect them to be comfortable with each other for some time.
Regarding names: I try to find something that means a lot to me at the time. If it's a movie, tv show, a piece of art. Whatever it may be. Mochi is named from a Disney movie and so is BB. Well she was supposed to be and got stuck with BB
since his name is Graphic Night you could try to find something that goes with that. You still have some time to come up with names. Do you have any picked out yet?
