It's definitely worth keeping in mind! Edwina, for example, rarely barfs up an actual hairball but there are sometimes small amounts of loose fur when she vomits. (Trust me, I understand all too well about checking!)Thank you for the info. I will definitely keep that in mind. She doesn't shed a ton and licks quite often and rarely has hairballs. I do notice hair in her feces (gross that I check, I know). I only checked since she started puking I was looking for worms etc...My cat does seem very anxious lately too, probably because she's not feeling well.
