I have 2 cats, brother and sister, who are 10 years old. My male Cat Damian, to this day, tries to suck on my ear lobe. He acts like a dog most of the time as he likes a lot of attention and jumps all over people. He always tries to get me to pick him up. As soon as I do, he goes for the ear. Every once in a while he is succesful, but then I get slober all over my neck. I have had them since they were 6 weeks old. I was told that their mother was hit by a car and died, and they were placed with another litter. So I am thinking that Damian feels like I am his mother and never grew out of being a kitten, cause he definately acts like one!
