Give me a kitty. Especially if I can spend all day with her! I have had dogs but I have always had cats. Generally, they are left alone all day leaving us to think they sleep all day and do nothing. Being captive they are probably bored beyond belief.
But since I had a back injury and have been home 24/7 I got to know my newly adopted 1 year old cat. And omg - she never sleeps first of all, she wants to play all the time (I thought by now she would want to just lay around), she hides behind walls and doors and jumps out at me, she stands on 2 feet if she wants to see what I am doing in the sink - most shocking of all is one day when she was using the litter box she puckered her lips (I guess it felt so good). We have been taught that cats can't do this - so not true!
She is amazing and I never would have known all she was if I was out working all day. Our cats are far more lively and interesting than we think they are! But they are captive which is unnatural - and so we have to compensate - but somewhere, somehow we were taught all they do is sleep.
