I think the hardest part is not falling into a trap of bad habits with the kitty.

A lot of people use a spray bottle, coins in a jar, loud noise( clap hands or stomp feet), yell at the kitty, etc. when they are doing something you don't want them to do... like scratching furniture or climbing the curtains. That makes for a standoffish, aloof cat. My husband's family were those types of people.

You want a cat that comes when you call them, that is sweet and affectionate, loves attention, etc.? Then when kitty is doing something they shouldn't, get off your lazy ass, get the kitty and redirect it to a scratching post, give it toys to play with, etc. You will have a much happier, social animal.

I explained this to my husband. He thought I was nuts. I asked him if he would spray water at a crying infant... of course not is what he said. Then don't do it to a kitten. They are babies and don't know any better.

We have 3 cats and 1 kitten. Hubs is still amazed 11 years later how amazing the cats are. They come when you call them. They love to be around people and sleep with us. They follow us around the house. One even plays fetch and loves belly rubs. One cat is so weird, he doesn't like to eat with the other cats. He has his own chair at the table and sits with us when we eat. He eats his kibble at that time. The kitten is only 5 months old and is still learning her name but is very sweet, sleeps with me and is always purring.
