Although my Sunny is only half aby, I think that he has many of the aby traits that everyone has mentioned above.

He loves to be up in high places.

He loves to talk to me and makes many chirping noises.

He loves attention from me- head & back scratched, belly rubs, me playing with him, cuddling on his terms.

He loves to run and play and is very hyperactive.

He likes my other cats and will lick their heads and give them headbumpies.

He loves to follow me around like a dog.

When he plays with his toys he'll pick them up with his paws and also carry them in his mouth.

He loves to play in water and is fascinated by running water.

He's also sometimes very needy.
