When I got my cat she was almost 6 months old. You would think it is not much and would be easy to bond with a young kitty. I bought her from a breeder but I suspect something happened to her before because she was scared of everyone and especially men. I was so heart broken, she spent few months just sitting under furniture and looking at the world with eyes full of hatred and fear.
I was so upset that I even wanted to return her to the breeder because I thought she just hates us so much.
Not to mention the horrible peeing problem. She peed on my pillow while I was asleep, as well as on every piece of furniture in the house, on my ned again and again and again.
But I tried to be patient and was nice and encouraging with her, whatever happened. Now two years later, she is a sweetest cat in the world and she thinks I am some sort of god creature which is flattering of course, considering all the effort I put in. I think the fact that I got a second cat also helped. She doesn't feel alone among big tall people.
I have to admit that she is not terribly fond of strangers but still the difference is huge comparing to what we started with. Again, I think patience and persistence are the key.
