Attacking your hands, shoes, and shoelaces when you try to tie your shoes is adorable when they are kittens. Keep in mind though, that they will still do it when they are 16-18 lbs cats. What you’re teaching them is that hands, shoes and shoelaces and fingers are toys and therefore they can be attacked. Now I don’t think you will enjoy a fully grow cat attacking your fingers, nor would you appreciate finding scratch and teeth marks all over your new shoes that you forgot to put in the closet. But that will happen unless you teach them that those things are off limits.
Letting your cat sleep in the bed with you is great, however, be prepared to be on their schedule because they simply do not care what your schedule is, unless you teach them what your schedule is. My bedroom if off limits for cats, no cats sleep in my bed, and no cat even walks into my bedroom even if I have the door wide open. They know it’s off limits.
When you allow cats to be dominant, they will be. If you allow them to be the king of the pride in your house, they will be. I am not saying that the posted movies and pictures are not adorable. They are, young kittens are hilarious and the things they do are worthy of posting because it is so adorable. The fact that they are so adorable makes it so hard to tell them no. Who can resist those adorable eyes right?
Cats, like dogs (and kids for that matter), need to be taught manners. If you don’t teach them manners at a young age, they’re not going to have them when they are older and that can potentially cause some major problems.
Be aware of what you allow your kitten to do, be aware of what you teach them. If you allow it now, they are going to assume it will be allowed forever.
