Hi! My cat just threw up green bile-like vomit that looked like there is grit in it. I came home to two separate piles of this as well as one with a hairball in it. He has thrown up hairballs before, but never with a gritty substance in it. He is acting normal otherwise.

Poor Salem. He may have eaten something that is gritty causing the vomiting. I can give you a home remedy to see if that helps. Withhold food tonight, then feed a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he refuses to eat the bland diet, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. I hope this helps!

The hairballs themselves can also cause vomiting. Try a hairball paste such a Laxatone or PetroMalt. Daily brushing may also decrease the incidence of hairballs. If the vomiting persists, have Max examined by your veterinarian. Discuss allergy testing and food elimination trials with your vet to rule out allergies or food sensitivities.

If it was just one hairball, I would keep an eye on Angel to make sure she doesn't vomit again or seem to be choking, and offer a little of her food after a few hours. Changing to a hairball diet, supplemental paste, or grooming her more often can also help reduce hairballs in the future. If she continues to vomit, or gags/tries to vomit or go to the bathroom and can't, I would be worried there was an obstruction from the hair and seek veterinary care right away.

That much vomiting in a short span is concerning, and being unable to keep water down is a good reason to get her in to be seen by your vet as soon as possible. Cats need to eat, they cannot go more than two or three days without food before they risk serious liver disease. The change in voice is even more reason to get her seen. It could indeed be a hairball, but since she hasn't produced one, if it is a hairball, it is one she can't easily vomit back up.
