The question assumes that animals have the same level of consciousness and self awareness as humans. There is no reasonable basis for that assumption. Animals form bonds with humans, but it would be wrong to say that they think about us.
I do believe that animals can be emotional. Dog are pack animals, which means that bond with others. When bonds are broken, there is an emotional reaction.
It is the concept of "Thinking" that supposes a level of congnition that I don't believe animals possess.
Someone once said, "Dogs have owners . . . Cats have staff."
Ok . . . the dog and cat bit is a joke. . . . . It would be most difficult to prove that pets spend time "thinking" about us, if by thinking you mean something on a par with human congnition. My assumption is that cats and dogs have limited faculties.
This is what I think what my rabbit would say to : "Stop asking me to lick you. Come and massage me now!" (cause I always ask her to lick me .. after a lick, she will position her head under my palm and wait for me to pet her haha)
Reading animals brains is easy. Humans are a little bit more difficult but not impossible by no means. They communicate with each other and rarely try to communicate with us, unless they are wanting our attention.
Why the hell won't he let me eat just one more turd?
I have a fish. He likes me. He'd never talk smack behind my back but then again he's a beta so he has to live alone.
I think they secretly hate us
they probably talk about the IQs of the people in that show, American Shore
maybe the same stuff but pertaining to us
