From my experience, a young kitten is more likely to bond with ALL members of the family. We adopted two Maine Coon mix cats from a shelter who were about 7-8 months old, and both of them took to me and no one else. When DH and I were dating, we adopted a 12 month old Siamese-Himalayan mix who promptly took to DH only and was downright mean to everyone else.
I always used Arm and Hammer cat litter, seemed to keep the stink down better than other brands. We fed them Purina One food. The Siamese had a bad allergy to food dyes, which we found out the hard way when the store didn't have our usual so I grabbed a box of Meow Mix. He was sick for days, throwing up red goo everywhere.
Allowing your cat outside depends on where you live. My first Maine Coon, Rosie, loved to be outside. There's a wooded area behind my mom's house and she would go back there and hunt mice and birds and whatever else she could sink her claws into. She was a fantastic hunter, and I couldn't imagine taking that experience away from her-it was such a huge part of who she was.
Kiku, our Siamese, was not allowed outside without "adult supervision" because he would climb up a tree and onto the neighbor's garage roof and tease their dogs. Then we started getting reports of "pet theft" on our street, so we kept the cats indoors unless we were right outside with them.
We do not have cats right now, and if we did they definitely would not be allowed outside. The people next to us have a boxer, the people behind AND across have pit bulls, and now the neighborhood watch group has started a trapping campaign because of the feral cat "problem". I don't think they are a problem, but perhaps it is worse on other streets. You need cats to keep rodents and other pests away. I would say the REAL problem is the overwhelming presence of European starlings that make their nests in awnings, overhangs, and chimneys

I just don't agree with the trapping because they are taking these cats to the pound to be euthanized.
In fact, call your local pound before you go anywhere else and ask if they have young kittens. Pound animals have such a short amount of time to be rescued from death. Around here it's 72 hours.
