I'm not new here just to this thread. Hopefully this is in the right spot. So I have a 1 year old cat that was a stray that we took in last December and and has been indoor since March, she had kittens in.March and all has been well. I just started to notice that her tummy seems kinda hard. The kittens still nurse once in a while but not very often. She eats well and has been no change in how she acts. I have noticed it firm for a few weeks. She has been spayed as well and all of them did have worms that we recently got rid of. Does anyone have any ideas on what could cause a firm tummy with no other symptoms at all? Thank you
