My dogs have muliple stainless steel water bowls outside. Long ago one was designated by Marley as his toy, so I let it be just that. Ever so often I have to clean it out and I decided to do just that earlier this week. He'd left it upside down under a large tree in the dirt.
When I turned it over, I found this girl, so I left the bowl upside down. When I returned with my camera and righted the bowl again, she was headed up and out of the bowl in my face (pic 1). Put my finger out to detour her and she headed back down to the bottom of the bowl (you can see the male at the bottom of the bowl) & at the same time she released silk and some weird sticky substance just on the tip of my finger.
It was like glue. I suppose I should have assumed they can do that, but I didn't - thought it was pretty cool.
She and the male have both been relocated so Marley can have his bowl back
