My cat can't eat because he has lost many teeth

[itineran]

My cat has only three upper teeth left, so he has trouble eating normal foods.

Does anyone know of special types of foods that a cat can eat in this situation?

I am going to start pureeing all of his canned, wet cat food in a food processor.

How old is he, why has he lost so many teeth, does he have stomatitis or any other condition, and what has your vet recommended?
