My vet didn't seem to pressurise either way as far as food is concerned. All he warned me was that sometimes the recommended quantities on the packets are an overestimate of what they really need so to watch out for excessive weight gain.

At the moment my 4 months old kitten is having a diet of primarily Hi-Life kitten pouches (or Purely when I couldn't get Hi-Life). He has either 3 pouches of Hi-Life plus a handful of dry food left out in the day, or some days I substitute 1 pouch of Hi-life for Applaws, Porta 21 (which he doesn't like so much) or plain meat/fish (eg poached haddock/coley, tinned sardines/tuna, roast chicken/lamb etc).

I only give him cat milk occasionally as a treat, usually he just has water (though seems to prefer drinking water out of my glass whenever I'm not looking than out of his bowl!)

Today I received some free samples of Whiskas, which is what he was on when I first got him. I gave him some for lunch but I think he's got too used to the better quality food because he mainly just licked off the gravy and left most of the chunks until later on when he must have been really hungry! When I give him Hi-Life or Applaws it disappears in minutes.
