This squirrel went nuts.

A blood-thirsty squirrel caused pandemonium at a Florida senior center, injuring at least three people during a terrifying Thursday afternoon rampage.

“We had a squirrel that entered our building and it’s in our activity room and it’s jumping on people and biting them and scratching them, so we need help!” a worker told a 911 dispatcher during a chaotic 3-minute call posted online by WFTV.

According to the 911 call, the bushy-tailed rodent made its way to the Sterling Court independent senior living center in Deltona, FL at around 2:30 p.m.

“We need some care for people here!” the caller pleads. “It’s still in there and the people are bleeding.”

One victim, included a lady named “Stacy” who the caller explained was “bleeding a little uncontrollably.”

At one point during the call, an injured woman can be heard saying: “I feel lightheaded. I don’t feel good.”

At some point, someone managed to toss the squirrel outside, but its unclear what happened to the critter.
