Varies wildly for me but usually whenever the opportunity presents itself, although it mostly ends up being cats. I always have cat food and water outside near my back door for strays. Two days ago I brought a can of wet food for a feral momma and her kittens on the other end of town. (Trying to make friends with mom, but not much luck so far.) Was leaving veggies out for a deer that was living in my backyard this spring until she moved on. Occasionally put stuff out for the birds when I can. I also don’t mow certain sections of my yard and my daughter’s yard much because the bees love the clover that grows in those spots.
