I have had numerous cats without teeth, and all have been able to eat everything, including raw meat (although i had to cut it into small chunks for Ginger). My neighbour was surprised at Sam eating biscuits cos he has no teeth, but he doesnt' let anything stop him, and prefers his wet with a bit of dry on it. Interestingly, I have two cats here with gum issues, one with teeth, one with no teeth, and the only one I have to mash food up for is the one with teeth. Unfortunately, it hasn't stopped Sam's red gums, but you can only tell when you open his mouth, you wouldnt know otherwise.
