Cats behaviour

[Kazzer]

I dont know if my cat is pregnant or not but every time I lift her up she meows. Her behaviour towards me has changed as well one minute she is getting petted and the next she is growling and hissing at me and I dont know what to do, please help.

She may be ill -- please get her to the vet's immediately!

I agree with Litchick. Take your cat to the vet asap. It could be the sign that a normally placid cat is feeling poorly. Let us know how you get on. Best of luck :)

I agree with the above, she needs checked out by a professional.  And if she gets the all clear, perhaps it would be a good idea to consider neutering her?

We had a tom that started this, he had an infection in his liver. Take your cat to the vet as you should catch this early, unfortunately we didn't catch it quick enough :(

As others have already said, this may be an indicator that she is experiencing pain. You really must take her to the vet IMMEDIATELY.
