Allow me to finish these comments for you.
Cats are intelligent enough to know... |
where the litter box is, where their food and water dish is, and whether or not they want some booty.
Dogs are intelligent enough only to drool. |
However, they are also intelligent enough to learn how to detect cancer, sniff out drugs and bombs, walk blind people around, speak when spoken to, and learn how to jump 5 feet in the air, backwards and upside down, to catch a frisbee. Not to mention, hunt, point, sit, lay down, roll over, heal, shake, and play dead.
A cat can learn how to dookie in a toilet... I think that's about the extent of it.
