Is it normal for a cat in heat to have abdominal swelling? My cat is 3 yrs old and we have been meaning to spay her, but she goes into heat so often it’s hard to find time to do it. She is currently in heat and has been for over a week, and last week she had shown asymmetrical swelling on the left and right of her belly. The next day it went down so I figured it was nothing serious and probably swelling from being in heat. Now it has been a week she is still in heat and her abdomen seems just ever so slightly fuller on the right and left and firm. She is crazy in heat and doesn’t show any signs of being sick, acting normal, eating drinking, playing and jumping.

Is it possible for a cat in extreme heat to cause extreme swelling of the ovaries to where they would be palpable? I’m worried it could be early signs of pyometra, or if this is normal with heat. Her cycles have gotten more intense and extreme, as well as longer and more often, which makes me think it could be possible her reproductive system is simply engorged with blood causing it to be palpable.

If that (the swelling) is not normal with heat then I’ll take her to the vet ASAP, but again she is not grossly distended, she just appears “full”. Also there is no chance of pregnancy. Thanks.
