Thanks for posting all of this info - it is so interesting.
My cats were fed canned food as kittens, but the vet told me to put them on all-dry food as this is apparently better for them. A year down the line one of my cats is overweight and I just haven't been able to figure out why - we don't feed him lots of treats etc.
These articles have given me a possible reason. I'm going to carry on reading them and rethink my cats' feeding regime entirely.
Thanks again!
