This is Oreo ("the black-and-white cat").
This is Ringtail ("the gray cat").
Both live somewhere in our neighborhood, probably in a shed or garage or under a porch, and are mostly feral. They visit us at least twice a day, usually at breakfast and at suppertime. When rain or snow is expected, they may drop in more often for extras in case travel conditions become risky.
We wish we could put little video cameras on their foreheads to see where they go and what they do. We hope that they, like most indoor cats, find a warm and comfortable place and nap most of the day. We've debated trapping them in our Havahart kindness trap and adopting them (after a vet visit), but Mattie and Little Debbie recoiled in horror when we mentioned this to them. So, the debate goes on. Meanwhile, my imagination worked overtime, and I wrote a story about them and the wildlife any uneaten food attracts. That's the February 2018 entry.
