I feed my cats on a partially raw diet. There are a few things to consider:

• Plain raw meat does not contain the levels of taurine and other important nutritional items that keep your cat healthy. Taurine is particularly vital as it keeps the cat's eyes, kidneys and heart healthy and can make them live a lot longer. Many commercial cat foods don't contain taurine either. Whether you choose raw or packaged food make sure your cat is getting taurine. Do this by checking the packet for taurine as an ingredient, or you can add taurine, or complement the raw diet with a premium dried biscuit with taurine (such as science plan).
• Whilst cats are well equipped to deal with the bacteria that we as humans can't cope with in raw meat, if you're feeding them meat from other mammals be careful choosing your source. For example, rabbits may have had their gut and intestinal tract removed but certain worms and microbes can end up forming cysts in the actual muscle/tissue of the rabbit and end up being eaten and passed on to your cat. One solution is worming them regularly (every 3 months) and alternating between drontal and milbemax. Basically milbemax kills all but one and so does drontal but the one each doesn't cover, the other does. Hopefully that makes sense. Your best bet is to buy fresh meat that is classed as suitable for human consumption. I've also been told storing it in the freezer for 3 months is enough to kill most of the bacteria/microbes.
• One of the potential benefits of feeding raw is that you can ensure your cats are eating organic food. i.e. without lots of nasty hormones in. This can however prove very expensive.

I've had no problems with raw feeding because I've been careful only to give them fresh meat. I mostly feed them raw chicken - and they seem to prefer things like chicken thighs as opposed to breast meat which is good because it's cheaper! Just make sure you're getting all the vitimans and minerals they need into their diet. You also need to make sure you're fastidiously clean. My two are terrible for picking up raw chicken and placing it on the floor before they eat it so I'm forever having to clean the floor with antibacterial wipes. Hard work but my two love it so much it's worth it!
