hi, my female cat is 17 years old. recently she has a clear
gel like substance coming out of her mouth. we had her to the vet, where he looked thouroughly in her mouth, found nothing. she also had blood work done, it came back everything normal. she is eating, slightly, and pretty inactive, cause of age im guessing. any ideas as to what this substance is? could it be dangerous to me and my family? please advise. thank you.
