Please beware if you live in an area where there is wildlife; such as, Coyotes, Mountain Lions, Hawks, Owls, etc......
This message is geared more towards medium to small pets; however, still beware if you have large dogs.
I just got done working with a lovely family. Their poodle was taken out of their yard in a matter of seconds.
They only let the dog out to go potty and then he comes right back in the house. Not this time.
They heard the dog bark and then no sigh of him. I got a coyote took him. Coyotes, and other wildlife can go over high fences so don't think that your yard is safe if you have a high fence. Also, birds of prey can easily take a small animal.
My suggestion- DO NOT LEAVE YOUR ANIMALS UNATTENDED IN YOUR YARD AT ALL IF YOU LIVE IN AN AREA WHERE THEIR IS WILDLIFE PREDATORS!
