I have two 1 year-old cats that are brothers. For a while now, they have been occasionally vomiting up dry food. Each cat will vomit maybe 2-3 times a month, and I haven't been able to figure out a pattern.
I got them a 'puzzle feeder' a while back to help them eat the dry food slower, and that seemed to help a bit.
Is this normal or should I be looking to switch dry foods?
