Peccaries are members of the pig family. When one died a camera was set up to observe their response. More study might be needed, but they certainly responded to the death and showed signs of mourning.

We accept that animals are sensitive, intelligent creatures that show signs of emotional depth. I am glad to hear that there is some evidence. Many people will not believe without evidence. If people come to believe that animals have feelings then we have a better chance to gain them  some rights.
