Beware of cat.

Mail carriers in Britain don’t have to worry about a dog when they deliver to one Bristol home, but they identified a jumpy cat named Bella as a “potential hazard,” the BBC reported Thursday.

Matthew Sampson, the cat’s owner, told the BBC that he was sent a letter by Royal Mail last week saying that the cat is a “threat” to staff.

"Your postman has reported that when he pushes the mail through your letterbox your cat snatches the mail and puts his fingers at risk of injury,” the letter said.

Sampson thinks his cat believes it’s a game.

"We've noticed over the last couple of days that the postman is very hesitant at putting the letters in and Bella thinks it's a game that he's trying to play," he told the BBC.

The letter advised Sampson to "restrain" his cat or provide an alternative space to drop the mail – or else they'll stop delivering to him entirely.

But Sampson admits Bella could be difficult. "As to restraining the cat - I'd no way dare."
