I have two cats, approximately the same age, 7 years.
For the last 6 years I gave them the same food, royal canin indoor adult cat food (those dry pellets / croquettes).
Recently, over the last month or so, I have one of the two cat vomiting daily, the other one has no problem.
Before that, that cat would sometimes vomit but would be fairly rate.
I tried to give food little by little to avoid him to eat too fast but seems to have no effect.
I've tried to change the food with those meat bag (similar to can food) and he does not throw up.
I then changed to another brand of this dry food pellets, and the cat is vomiting again.
Besides that, the cat seems healthy and I did not see any change in behavior.
Any idea what could be the reason and how to solve it?
