A cat's ability to reason isn't there. Their life consists of eating, sleeping, grooming, and playing with their friends, if there are other critters in the house. When one goes, and there are only two, the other grieves. They have a lot of the same emotions we do, but don't know what to do about them. Our cocker spaniel looked everywhere for the cat after it died. She looked in cupboards, closets, under the beds, on the beds... everywhere that the cat had been. She looked so sad... So we got a kitten in a few months. The kitten looked just like the other, only on a much smaller scale. She bonded with that cat immediately. Last summer, that cat became ill. He was only a few years old. We took him out in a cat carrier and brought the carrier home without the cat. Needless to say, the cat had to be put down due to kidney disease. This time the dog actually cried. So, I go to the shelter and am chosen by a little 8 week old tortoise shell kitten. We brought her home, and the dog quit looking for the other. However, she has little to do with this kitten. It is like, "I am not going to get too close, because they go away and don't come back." I wonder what will happen with the cat when the dog goes. She is almost 10...
