I dont know why she does it, maybe because she likes being with the dogs? Or just the fresh air? I dunno.
My foster kitty Sugar likes to run out also, BUT, she doesnt roll around, she runs around from tree to tree scratching and hopping. I try to keep a spray bottle with me, and I spray as I walk into the door, or when I walk out, and it usually stops her momentarily
Sundae is beautiful by the way
