My male & female kittens were neutered today and since coming home, they are hyper and acting strange. She keeps tipping her water bowl over, pulling her blankets out of her bed, it's impossible to stop either from charging around/leaping off furniture. It's like they are dogs with rabies. Is this normal. They are playful normally, but not frantic like this. She wants to sit in her carrier basket we took her to the vets in so not had the chance to put it back in the garage. He's not quite as crazy, but just headbutting doors.
