Sounds dumb but I watch my backyard ecosystem a lot. Like a LOT. I smoke on the back porch so like I say. A lot. I’ve carefully cultivated this nice little nature preserve and have watched the birds raise families. All families that return year after year and grow their own families. I recognize them and know their patterns and that’s helped me to feed them and their young at the times needed and in a way that minimizes their vulnerabilities. Same with squirrels, possums, etc.
It hurts when you see one of your babies fall prey to something bad. Hawk, neighborhood cats, nature, and worse, humans.
But I began to recognize that’s the price I have to pay to be involved. Realistically I shouldn’t be involved and in an ideal world humans would leave all animals be, but I live in suburbia and animals are sometimes dependent on us here.
But being involved is a precious thing and sometimes it just hurts. Remember that you’re likely right about the kitty falling prey to another animal. But don’t fault that animal as they are simply doing what they know. Just be ultimately grateful that nature recognized you as a safe person/safe place and that’s a pretty awesome thing. Let that thought lift you up when the dark underbelly of nature shows itself.
Or be neighborly and go over with a couple big blocks and tell them you noticed that's sketchy and wanted to help out!
