I've changed my cats from ava (premium pah brand too) to applaws, my cats were eating it very fast. I also stage the food, so they get a certain regular amount all through the day (first top up 5:00 2nd 12 3rd 4 4th 9) if your working ect then just divide it up diffently. All I can help on with the food your cats have (I've picked pah staffs brains alot!) is do you buy the grain free version ? As grain is a "filler" and not very good for cats - before I changed over to applaws I did consider Jw and what put me off (from what I can remember) was it had less meat content than applaws for the grain free and grain version? And you may also want to check the meat content in hilife as my dh checked out there dry food yesterday and he said it was about 5%?! My cats are on purely from pah (not too expensive) and that's got a high meat and no grain. Sorry if that all seems confusing, i absolutely hate choosing cat food there's too much information to think about! Good luck!
