This will mostly be about interpretation and non-human semantics to please don't take it a personal, but disagree.

I really hate to get into the whole issue of primative v. advanced or more developed, but when it comes down to how smart cats and dogs are it really can't be avoided. I think for most pet owners it's not a question of "are" our pets smart, but "how" smart are they.
I'm not suggesting in any way that my cats could harness fire or figure out Calculus, but dogs can be trained to smell certain scents and comminicate that fact to thier handlers, and my cats know that fresh water comes from the spigot on the vanity. These are things that take both learning and discernment.

As a cat person, I'm going to have to disagree based on the stereotype that cats don't "love" their companions, but instead "tolerate" them. Back when I used to let Scarlett out to roam my apartment compex, she was apparently taken in by some neighbors of mine 3 stairwells away. They decided to put her on their balcony and when I came home from work, she started plaintively meowing at me. I knocked on the door of the apartment with no reply and after about 10 minutes of trying to coax her off the balcony - she jumped nearly 30 feet. I think she migh have hurt herself in the attempt, but the vet said she was O.k.

This is the crux of the issue. Many animals do exhibit moral thinking, but just on more base levels than humans do. They simply lack the more developed brain corticies to choose, say, a vegetarian lifestile despite being evolutionarily omnivores. This lack of, ugh... I hate to admit this - "free will" doesn't diminish their intellectual capacity in the gestalt in the least bit.
I'll just step over the line from evidence to belief in seeing primates like Koko as actually being able to express thought and emotion (I'd ask that you check her reaction to "All Ball" being run over) rather than attribute them to simple autonomous reactions. Maybe I'm giving to much intellectual credence, but I don't see much difference between the cute redhead I saw from the OKC bombing mouring her children and the footage I've seen of a Cheetah mourning the loss of her cubs.
