In a nutshell NO , we do not advise this as it can lead to digestive problems. Two types of food take different amounts of time to digest and kibble is very often packed with grains, cereals, cheap fillers,, by products and chemical preservatives. Feeding carbohydrates with protein can lead to weight gain and it defeats the object of feeding your cat with a healthy species appropriate food.
Poo is a good indicator of whether all is going ok. An average cat will poop once every 1 to 2 days on a raw diet. It should be small and well formed. If you find the poop is too crumbly then is too much bone in the diet and it will need to be reduced. Too much bone can cause constipation.
Always remember to follow the same hygiene standards when preparing cat meat as you would for yourself. This will ensure feeding raw remains a safe practice.
