calico cat/smells

Question
I have a calico, she is about 4 years old. Recently in the last couple of days, she started smelling in her vaginal area, though she was spay when she was just little.  I don't know if this is normal or if there is cause for concern for a urinary problem or a possibility if she could have gone into heat again, it really smells like she is but i know that could be impossible.  Have any answers?

Answer
Cynthia,

She may have a uterine infection. Does she have any other symptoms? Is there any discharge?

This is a question that you should ask your vet. Give him a call and explain the symptoms and see what he says. She may need to be examined to know for sure.
