I really do think, that in most cases, it hasn't a thing to do with the owner, but instead totally with the cat. My two current cats are basically secure with me. They let me do anything to them, including brushing their little teeth. It took some time to build up the trust though. I do believe that some cats come to you pre-programmed, if you will, and will never allow you to do anything to them. My last Aby would never, never open her mouth. So pilling was out of the question. These two Abys don't mind it at all. I think personalities come in all shapes and forms in cats just like people! I would like to believe that I can control my cats, but I suspect they really control me!!!!
