Our little Tabby Samantha is plagued by a lot of snot/mucus, has been for awhile now which we think is most likely allergies. She was one of the cats that we took in from our backyard years ago, she was born here along with her brother Socks and her mother Sabrina so we know her history. But she gets very blocked up, sneezes at times and a lot of snot comes out. Aside from taking her to the vet, which we will do if needed, but I know they always like to give them an antibiotic shot and a lot of times I don't think it is needed and can be harmful, what could we do for her? We do try to add Lysine to their food which helps, but she doesn't eat much wet food mostly dry so we add it to that when we see that she is eating. She also always has had a sensitive stomach, she eats and throws up pretty often, we tried the sensitive stomach food which didn't seem to help much, but otherwise she is fine, very affectionate little thing so we would like to try to get her some relief from this.
