So i have a stray cat around neighborhood that i take care of ffrom time to time. She is around 4 years old, and just about a week ago she gave birth at my home. But after the labor, she had this kind of a lump around her primordial pouch. This lump is suspiciuosly big but soft and squishy when i touch it. She doesn't appeared to feel pain when i touch that, and doesn't look like sick either. But i still worried, because all of her previous labor, she never had this lump before. Sorry for a messy writing and a broken english, i hope you guys can help me out!
