Critters?

I took this photo yesterday but got too deep into my book last night and forgot to post it. There remain two blooms on the Christmas cactus.
Minus 35 C when I went for groceries this morning...after shovelling the driveway. Temperatures are forecast to “warm” up a bit by the middle of next week which should mean the end of polar vortex. Vaccine and spring are not far behind.
