I'm looking for some advice regarding my 10 month old cat, Maci. Maci sounded like she was gagging and then vomited up a clear-yellowish liquid this afternoon. This is the second time she has done this in about 2-3 weeks. She seems to be eating and drinking properly. She is active and playful and seems to be having no trouble using the litter box. Maci is a completely indoor cat, so she hasn't gotten into anything that would upset her belly outside. She is due for her 6 month wellness visit at the vet, but I was just looking for some ideas as to what could be going on before I take her.
