LOL. that is SO true. We have two cats...they are indoor/outdoor. Many is the time we have watched from the window as we observe them "hunt" a squirrel...as we are indoors begging them, KILL IT, KILL IT! It has never happened. They crouch, slink, and stalk as if their very existence depends on capturing the squirrel...only to eventually just sit. 6 years now. Never finished the job. We're pretty sure they are mentally "limited". :)
Our vet has indoor/outdoor cats...our cats have all their rabies, leukemia shots..and all their claws. :)
LOL!
A few years ago we had our grownup cat, a young cat (4 months) and a puppy. We have an above ground pool with several shrubs surrounding it.
The three of them discovered a mouse and it was a comedy of errors with the two cats and puppy trying to catch the mouse. No one got it and I think the older cat was very embarrassed by the whole thing.
It was very fun to watch.
