Cats are imprinted in their first year of life as to the types of foods to eat.  This makes some cats seem finicky when they are simply doing what nature taught them to do.  Cats that have eaten nothing but dry food or even canned food are often a challenge to switch to a raw diet. But it can be done  Cats that eat other foods (meat, fruits, vegetables, cheese) will be much less of a project.  It might take days, weeks or even months.  It’s worth the effort!  Cats will starve themselves, and they are not good candidates for the tough love approach.  Some very serious conditions can occur if cats do not eat for an extended period of time 

That first bag of raw food may last a long time:  put it in an air tight freezer container to protect it.

Slow & successful method:  move away from a dry food diet and toward more canned foods.  Consider dry food to be a snack only, not left out all the time.  Mix a small amount (1tsp to 1 Tbs) of thawed raw food into an entire can of canned food. Work your way up slowly to add more raw food to that canned.  Offer bits of other kinds of fresh food that you are eating too.  They may be refused, but one day they won’t.  Some cats take to a raw diet right off, some take 3 to 6 months and some take a year to welcome raw food to their diet. 

This method may also be used with dry food:  in that case use an even smaller amount of raw food to a small amount of dry.  The canned approach works better, but if your cat absolutely refuses canned food it will be a better way to start. I have even started some with freeze-dried raw first, and then switch them over to fresh raw.

Serving tips:
Serve food in a flat dish, cats whiskers are sensitive and a bowl will interfere with the whiskers and may keep the cat from considering the food.

Trickery has been known to work with cats: put the food on YOUR plate, or hide it in a location cats know to be forbidden ... creativity helps!
