My cat has suddenly gone from a timid house cat to apositive tiger,going out in all weathers, fighting and winning, screaming to get out of the house. Its like she has had testosterone lnjections.

Is she spayed? Is she healthy?

She was spayed as a kitten,and is otherwise healthy

I think I answered in the wrong place

You answered in the correct place.

How old is she?

Wondergirl is a cat person; I'm a dog person. She knows what to ask! I'm just guessing.

You did good, Judy. No matter what kind of animal it is, we always need to ask common-sense questions to find out more information to help us give the best answers. It works for horse questions and pet elephant questions too.

Are you supposed to spay your pet elephant, too? Wow, I'll bet that creates some PROBLEMS, like how do you get it to the vet's, and back again ?

Back on topic... Sudden personality changes may be result of a brain tumor. Meningioma, particularly.
While testosterone participates in male behaviors, it is not the only source of aggressive activity in animals. Aberrant behaviors of all sorts can and do arise from abnormal brain activity. Errors in correct interpretation of one's surroundings or self can result in aggressive behavior, or worse. Closer to a more common likelihood are health changes or aches and pains that come with aging.
Or combinations of...

As usual, your vet is the place to start. You may not wind up staying there, but should be a jumping off place. Considerations, first... set a budget for diagnostic procedures (including exams and office visits) and then one for therapy, if any. Both could easily run into 4 figures. (not counting decimal places)

If we neuter most of the bull elephants (easier to do), there won't be a problem. And you get him there while he's small and can still fit in the back seat of your vehicle.

I agree with paleo--time to see the vet.

Actually my vehicle doesn't have a backseat so I'd have to take a bus. I suppose that could work. Wonder if the elephant would have to pay full fare?

Yes, time to see the Vet.
