Cat has the perfect reaction to discovering he's been neutered

A cat woke up after being neutered, and noticed something that used to be there was gone.

Six-month-old Milo went in to the local vet for the routine procedure Bob Barker spent decades reminding all pet owners about -- but he didn't seem so excited about the outcome.

When the freshly fixed feline discovered what was missing, his lost it.

"He took about a good hour or so coming around," Milo's owner, 58-year-old John Reed, told Metro. "He looked down and realized they were missing and let out this almighty screech. He carried on looking down and staring for ages."

Reed added that whenever he looks at the perfectly timed images, he can't help but laugh.

While Milo's reaction may make someone wonder whether castrating cats is the most humane move, most experts agree that it's the right call.

As the ASPCA notes, "In addition to the many health benefits, spaying or neutering your cat ensures that he or she won't contribute to the feline overpopulation problem. Even a cat who lives indoors may escape and produce kittens if not sterilized. Each year, millions of homeless cats are euthanized or end up in shelters due to a lack of good homes."

Looks like John was just putting Milo's health first.
