My cat vomited twice once yesterday and once today. He threw up his food. Can this be because of hairballs? He does shed a lot.

If there is not a wad of fur in it, it's not a hairball.

Could be a touchy stomach, could be nausea, could be the food was bad. Could be he ate too fast and the dry food puffed up too fast and he had to barf.

If it continues, contact your vet and ask for suggestions. Ask if 1/4 tablet of Pepcid A/C once a day (the only cat safe one) will help.

It could be. Once a day isn't so bad if it's not a continuous problem. Get him some hairball paste.

It could also be an allergy to some ingredients in the food, cats develop allergies fairly easily. If you go for a high quality brands, the cat would be less likely to come across the allergens from the filler in the food, and since it will be more nutritious, the sheding should reduce as well.

I wouldn‘t really recommend feeding any dry food. Cats are designed to get their water from food. That's the way nature designed them, they have low thirst drive. When fed dry, they won't drink enough to compensate for the lack of moisture. They will only consume about 50% of the water they should be having. This can lead to kidney disease, UTI, crystals, blockage, renal failure and more. Especially since you have a tom, this is crucial. Male cats have a narrower urethra than female cats and are more prone to blockage from the crystals.

Free feeding also contributes to obesity. And the fact that dry food is over-processed means, that most of it’s little nutrition has been already destroyed, leaving almost no nutrients for your cat. It needs to eat more to meet it’s needs, and in the process consumes more calories from the fillers.

Btw wetting the dry food will not help. There’s bacteria on the kibble and the water would just allow it to grow.

The only way to give the cat it's natural hydration is to feed it wet food only. pets question and answers,www.5d2d.com

But some wet foods are not of a very high quality, either. That goes for most commercial foods. Just like the dry, they are often made with cheap fillers such as corn, wheat, soy, rice etc. These are not a part of cat's natural diet (it’s an obligate carnivore
