I posted this once before a long time ago, but I think it's worth it again. I cut it out of the paper years ago and it's up on my fridge.

Hear out humble prayer, oh God, for our friends, the animals. Especially for animals who are suffering; for any that are hunted or lost or deserted or frightened or hungry; for all that must be put to death. We entreat for them all thy mercy and pity. And for those who deal with them, we ask a heart of compassion, gentle and kindly words. Make us true friends of the animals and so to share the blessings of the merciful.
