It really makes you wonder sometimes doesnt it! I know every cat I've ever had hates to be alone. They all sleep together on my bed, and eat together...all of mine would be lost without another cat for company! It's funny when my 2 cats that are allowed to go outside come in, Oliver waits at the door and jumps all over them and will fall down right in front of them and lick them to death. Here's a picture of oliver and Jack sleeping in my chair
