Where have they gone?

I haven't seen any of the outside cats. It is both a concern and a relief. I fear the saddest - they have been rounded up and euthanized. But how am I to know? We also have a hand in this- we have begun feeding them further from our house. They use the front dirt as a litterbox and it stinks to walk onto the front porch. This is not a good thing of course. I don't see them on the dumpster in the alley. There is little evidence of them under the shed. The truth is, there were too many cats. They had hard lives - but we tried to at least feed them and help them brave the elements with a couple of shelters. I'll certainly update on the situation if it unfolds!
