They make HAIRBALLL FOOD now...Purina and Science Diet specifically has the hairball brand. I use it..they love it. Also, a couple times a month, give kitty a syringe of mineral oil...just a couple CC’s. Do not give it around the time of his regular meals though because it prevents absorption of nutrients...but this will help his constipation.
2 brands to stay the heck away from. Science Diet has had many recalls and complaints. Purina is just crap (I still carry the guilt of giving it to my lost kitty).
Look up family based cat foods. DO NOT buy any cat food in the super markets, they are all crap. You must go to a local pet store to get the good stuff. Yes, it costs more, but in the long run, the cost of the food is MUCH less then vet trips.

He was on the Science Diet Hairball formula. We picked up a bag of “Blue Buffalo” grain free. I threw out all of the old dry food except for a 1 gallon freezer bag so I can mix a little in until he gets used to the new food.
We brought him home and fed him. He devoured some wet food and then turned to the dry stuff. He seems to have picked out the new food and ignored the old stuff.
I’m just glad he didn’t need to get cut open again!
