I think because the squirrels are in a city area, they are probably pretty safe from predators, both the human kind and animal. However, the cars could be an issue!
Costco usually is one of the first to display the decorations and the exceptionally big ones. I wouldn't be putting them in my yard because of their size plus with the winds we get in the fall and winter, we'd be chasing them through the forest or peeling them off of a tree they landed on.
Thank you for stopping by. Take care!
