Vet said, do the softened dry kibble (I forgot to ask her how long to leave it out), any complications or concerns to call right away, and even if all was well, to call her on Monday just to let her know that.
307 tooth is lower left premolar. It was in process of reabsorption. I've been trying her with various brands & styles of wet food to no real success. Thank you for your response, it gives me some insight towards what to do here.
Water added. My cat had her 307 tooth removed yesterday and is typically a nibbler throughout the day on dry food. So it's been a bit of a challenge not having a known set feeding time.
