When a Reddit user's security light came on at 1 a.m. this week, he peeked outside and saw something truly adorable: fox cubs playing with his dog's tennis ball.

The man stayed up watching and recording the playful cubs for hours and said the loss of sleep was totally worth it.

Foxes aren't the only wild animals that enjoy playing with dog toys though.

Recently, photographer Pamela Underhill Karaz photographed a coyote playing with a stuffed toy that belonged to Karaz's dog. The animal tossed the toy into the air and chased after it for about 10 minutes before running off into the woods with it.
