Having some cat issues..please help!!?

I'm curious, what are you feeding her?? The reason I ask is because I had a female cat that did that and I was feeding Purina Cat Chow (but it was a specific one like indoor formula or something idr) and was told to switch to regular PCC as soon as I switched, she stopped puking NO LIE...I couldn't believe it myself...doesn't mean that's the case with yours, but my cat was a female and did the same exact thing, and I thought hairballs at first as well but it progressively got worse, and quite frankly I was sick of cleaning it!! So maybe bring up to vet what you're feeding her??
