Sure you've heard of dangerous dogs, but how about a criminal cat? A cat, once condemned for attacking a person and a dog, is now accused of repeating his crime.

Hoppy is a large, black, adult male cat, who lives in Minneapolis on Drew Avenue South near West 39th Street with his owner, Lee Noltimier, 82.

Two years ago, the city of Minneapolis almost put Hoppy the cat down for being dangerous. But now, the city says, the cat is in trouble again.

Noltimier says his 19-year-old cat is too old and too afraid of people to ever cause them harm.

"Hoppy doesn't bite, he doesn't scratch," he said.

But some neighbors and Minneapolis Animal Care and Control disagree, saying the believe Hoppy is potentially dangerous.

"A declaration isn't a death sentence it's basically putting the owner on notice that they're animal is showing signs of aggression, that's a threat to pubic safety," said Dan Niziolek with the agency.

The city first impounded Hoppy in 2007, when a man says he was charged by the cat while walking his dog. He says Hoppy forced him to the ground, scratched him, and bit him.

The victim says even had to go to the emergency room. But even he told 5 EYEWITNESS NEWS by phone Wednesday that Hoppy doesn’t need to be euthanized.

The city ordered the cat be put to sleep after the first incident—which would have been the first time in city history for a cat to be killed for being deemed a dangerous animal. But Noltimier appealed the case and won.

Last month, someone says Hoppy struck again. A man says he was walking his dog near Noltimier’s house when Hoppy pounced. The city once again took the cat away from his owner.

While Hoppy is now back home, the city has put conditions on his freedom.

"He must be micro-chipped, stay current on rabies, and the most important requirement, he has to stay on harness controlled on a leash at all times he's outside," Niziolek said.

Noltimier believes it's a case of neighbors attacking him, not his cat attacking them.

"Gossip is easy. Where's the evidence?," Noltimier said.
