One really cool cat was found prowling the streets of New Jersey this week.

The exotic Savannah — a hybrid between a domestic puss and a serval, a large, wild African feline — was discovered Thursday morning in Paterson, CBS reported.

“I cannot believe what I see, and I ask her ‘look at this,’ and I saw it’s not a regular cat,” one woman who saw the cat told the station. “I don’t know what it is.”

“That is not a regular cat,” added another woman accompanying her. “That is something like a puma.”

Animal control officer Lysa DeLaurentis told the station that these cats could grow to double or triple the size of a house cat — but they are legal as long as they’re at least one percent domestic cat.

A man told the station that he knows the cat’s owner — a man who had left his window open, allowing the feline to escape.

“The cops know him, everybody knows him,” the man said. “He’s always on the window. Real nice cat.”

The feline was taken to Wildlife Freedom Animal Rescue in Wanaque.

This isn’t the first Savannah to get loose over the past month.

On Feb. 26, another one went missing in Marina Del Rey, California. Since it disappeared, the owner had search and rescue teams, as well as blood hounds, canvassing the area — and issued a $20,000 reward for its safe return, Fox 11 reported.
