Yes, I do. Humans are very arrogant about what constitutes intelligence. I think animals are much smarter than most conventional wisdom allows, but they are smart in different ways and have different priorities than we do.
My dog Mackie (whom I have raised from the age of 10 weeks) and whom I have spoken to as a regular person since that time understands a wide range of human vocabulary. We were at the dog park one day, and I called out to him with a complicated set of instructions that involved conditions. A woman walking nearby heard me and laughed, saying “Yeah, sure, like he is going to understand that.” Mackie then did exactly as I had asked him to and the woman was amazed. I hadn’t really given it much thought, because that is how I have always spoken to him.
My husband was surprised one day when we were in the car. Mackie was panting and I looked over my shoulder and said, “Mack, if you move to the other side of the back seat into the shade, you will be cooler.” Mackie got up and moved over.
I just wish I could understand what he was trying to tell me better. Dogs communicate mostly via images, and I, being very verbal, am not great at receiving pictures. So, our communication is more one-way than I would like. I have learned to differentiate his bark tones and to listen to him when he is reacting with his far superior scent reading.
On the other hand, when we got Kobe, our adopted ex-racing greyhound, he did not speak English at all. Now, in a little less than a year, he is much more responsive, but I suspect it will never be the same as a dog I raised from puppyhood.
Cats, by the way, can develop a human vocabulary of about 23 words (to dogs some 250). I am sure your cat is sommunicating with you. Their thought processes are even more different from ours than dogs though.
