My RB cat Pishi had hardly any teeth left in the end and swallowed everything. She did throw up all the time, but that was because of her having a stomach tumor which was diagnosed shortly after we took her to the vet.

Eddy never chews her food. No matter what she eats. She never has problems.

Rudie eats fast, a lot and chews very loud. As if it's important for me to ask him if he's enjoying his food. The only problem he has with eating so fast: he gained too much weight within one year and is now looking like a blown up balloon on legs.
