The purpose of the 4 year lifespan was to prevent the replicants from developing emotions and eventually get mad at the fact that they're are essentially slaves. I doubt Tyrell would see a need to put the 4 year life span in the animal replicants like the snakes and owls. So I wonder if those animals can die of old age.
Not sure if they age, very possible since it seems to be genetically created like the sanke. The earlier Replicants did not have incept dates. The incept date was created to like you said to stop that from happening when it became a problem. With Rachel (possibly Nexus 7) they had memories added to help pad it from the other side as well. To make them feel like they have lived a longer life then they actually did.
