The racoons don't touch my pond except to drink at the very shallow end that is the walk out, I see their prints there. Other than that they leave it alone, don't mess with the plants or anything.
Now the heron, different story lol, I saw one about 5 miles from here, it has not been back here since that one visit, but my fish are still hiding under the floating liner (around 10 x 5 counting the two pieces). The pond looks empty to a flying bird.
My concern with the fox, is missy being the great toothless yorkie hunter, would chase the fox, no concern for her safety if she saw it. She is one great hunter, we can be on a full run in the yard, she slams on the breaks sticks her nose in the air and sweeps back and forth until she finds the scent she picked up. Loves to try and get the mice, moles, voles what ever is around. Rabbits are her favorite.
Yep love having the fox around we have a ton of rodents.
