About a week and a half ago my cat had started dry heaving, seemed like he was trying to bring up a hair ball but nothing ever came up. It happened again a few days later so I bought some hair ball gel and gave it to him for three days as instructed. Still no hair ball. I had to bring him to the vet after this for conjunctivitis (which is all clear now) while he was there, vet said his breathing was normal so she wasn’t concerned about the dry heaving, we both assumed it was hardball related. Well I’ve noticed that he is still doing this dry heave at least every other day. It lasts only about 20-30 seconds, nothing ever comes up. He is acting, eating, and going potty all normally. Is this just something cats do?! A tickle in his throat?! I’ve looked up everything and for everything it could be, he doesn’t have the other symptoms that comes with it. I’m at a loss. Should I bring him back to the vet just to be on the safe side? Thank you so much in advance!
