I've had a few cats in my lifetime and have been around even more. Lost some, given away some, had to leave others behind.
Present day: I have two male cats, they are brothers. Both around the age of 10 months old.
Felix and
Shadow (Ignore me.)
(Note: Pictures taken at different times. Felix was barely a month old, Shadow was about 8 months old, respectively at the times of these pics.)
They are both nearly all black with a white spot on their chest. Felix's is more prominent, Shadow has a few stray white hairs on his chest. They are almost identical except for size and facial structure. Shadow is a bit bigger and a lot heavier than Felix and looks more...Siamese or something in the face, Felix just looks like an average cat of average size except his coat is shinier and softer than Shadow's.
They have another, smaller brother named Cheech. My mother currently has him. His white spot is a lot bigger than Felix's and he closely resembles him.
Felix is very anti-social to pretty much everyone except me. He doesn't like people to hold him, he doesn't let people even pet him very much but he's always hanging around me and will just lay there like a baby if I pick him up. He's also very vocal, will howl for me if he can't find me. Very playful too. Shadow is the attention whore, basically. He will suck up to anyone and flop down at your feet when he wants attention. When you're sitting down, he'll jump onto you and do it again if you push him off you. Also very lazy, doesn't like to play much.
Cheech is a mix of the two. Very fiesty, very attention loving.
