I want to try my boy on raw to supplement his dry food as I can't find a wet food he likes.
Hi Mymblesdaughter
I guess it depends on what dry food your man is getting. If it's a complete food and you're just supplementing, then simply raw meat will suffice, but if your dry food is supplementary, then you'll need to either find a complete diet like Natural Instinct as Gillian suggested, or make a raw meal consisting of meat, organs and bone.
By making your own you can "try before you buy" in small quantities and don't need to order online etc.
As Gillian said, supermarket meat is fine (modern technology means most meat is fresh and healthy) but you'll need to do a bit of work...I suggest a mix of 80% meat (chicken, beef, lamb, pork, etc), 10% bone (your boy will get through a chicken ribcage/wing with ease if he has his own teeth), 5% liver and 5% other offal (kidney, heart, etc).
My opinion is to cut this into chunks (start small and work up to big chunks when your man can handle it) rather than grinding into a paste or mince. Apparently by grinding you're reducing the amount of taurine in the meat (an important amino acid in a cat's diet) and exposing more of the meat to oxygen which can cause the meat to spoil.
I wrote a brief review/guide with new pictures on Raw diets here:
http://www.purrsinourhearts.co.uk/index.php/topic,42407.0.html that might help but there are loads of good sites to read up on. Try different meats, start slow and make sure your cat's getting fresh meat (or meat that has been frozen and defrosted) as they can't deal with "off meat" like a dog.
Most supermarkets sell a good range of meat and offal but you might struggle to get heart. If you have a local butcher, you can save yourself the hassle of chopping the meat and can get a good variety. You might also get a good discount if you buy off cuts at the end of the day.
Good luck, have fun and enjoy the new menu! Give me a shout if you need help with anything and let us know how you get on.
