I know for a fact how important it is bonding with your cat from day one. For instance a veteran pet owner will tell you that cats *do* “bond” with humans. In addition but only particular felines, and will actually “choose” a person in the household to bond with. For example, the kitty you picked out for yourself might bond with your roommate instead of you. I know when you are sitting and want your kitty on your lap and instead your kitty has snuggled with the roommate instead. For instance there’s no real explanation for why a cat chooses a particular person to bond to it’s their voice. It might be their mannerisms, or perhaps it’s just the way they “handle” the cat. It could be that the person is more gentle.

For example they might be a little more forceful (sometimes older male cats
will “take” to men and not women, and vice versa for females). I would say there’s the interesting notion that cats are psychic and that they bond to a particular individual because of a aura. For example at kitten will avoid someone if they give of a bad vibe per say. Most importantly there are many people who have owned felines that will attest
to this. I know there’s no real data to prove that kittens attach themselves to humans for reasons beyond physical survival. Besides most kitty owners know that cats do form affection for individual humans, and sometimes for reasons that just aren’t explainable in human terms.

Most importantly the kitten trees will help keep kittens cool in the summer and warm in the winter months. For instance you can create your own configurations of toys to keep your kitty entertained. Emphasis on easy to clean kitty toys with soap and water.
