Do animals have souls?

This is the result of a quick search on the definition of the word 'soul'. Goz, in her post, said that the word, to her, implied immortality. According to the search, the word 'soul' does not always imply immortality, but a number of other things that define a living being. And, logically, it would follow that a dead being would not have these mental abilities.

I would say that, as much as I would like it to be otherwise, the soul of a being would cease to exist when the being dies. As to where to draw the line of what level of life has a soul - like a cockroach, an insect - I don't know, but think that if an organism can sense pain and be trained by repetition of an activity, such as a maze, then it could mean that organism has a soul. This is purely subjective on my part. And I do not feel that it implies immortality. It is what I would call sentience.
