Cat acting weird (bite, house, vet, floor)

[Emilyvanleeuwen]

We got a new cat about 4 weeks ago. At first she was really shy, but after a few weeks she became more cuddly.
But this morning when she woke up, she suddenly started acting really weird!
She won't stop running around the house while making weird noises and then starts rolling on the floor. When I come near her she will roll on her back, grab my ankle and bite and pull my sock (in a playful way).
Normally she's quite calm.
Does anyone know what's wrong with her?

Probably in heat. Don't let her out (and you have to be extremely careful because a cat in heat WILL get out, and then will get pregnant).

Call the vet on Monday and book her in for a spay as soon as possible.

I agree that it sounds like she is in heat. Off to the vet ASAP.
