Lizard Moon, I have a number of cats, and a dog, and have been feed them raw for a number of years, so it's probably fair to say I have prepared and served up literally thousands of raw meals. Nobody in the house has been poisoned yet.
First, I assume the same food safety precautions I would when preparing raw meat for my own dinner - feeding only 'good' meat. The dog can manage meat that's on the turn (and does with great gusto) but the cats won't touch that.
Not that everyone has to go to these extremes, but I actually have a separate fridge for my pet meat. This was more serendipitous than deliberate - I moved house, my fridge wouldn't fit in the fridge nook in the fitted kitchen so I bought a second fridge and the first is now dedicated to beer and food for the animals.
The pet meat I buy, because I buy in bulk, can bleed a lot when it defrosts, and having a separate fridge allows me to clean up easily if that happens. So here's a tip:
*Always defrost pet meat in a bowl or other container in your fridge, so if it bleeds it won't contaminate other food stuffs.*
When I handle the pet meat, I use standard precautions - I wash my hands before and after I touch it, I use a meat specific chopping board and when I'm done I wash the board and the knife with very hot water and soap and then I wash down the counter and will use a surface spray.
*Take the same precautions with pet meat as you would with your own meat.*
As for feeding, I have a range of cheap ceramic dishes I feed my pets on - they don't have one bowl. Subsequently they get a clean dish at every single meal. My cats have a separate room in the house and there's lino on that floor, so I feed the cats in their room and if they drag meat around they do it aroud the lino in their own space. Every morning before feeding my cats I clean through their litter trays, collect the previous night's dishes and quickly swipe the lino with a mop that's been well wrung out in a solution of dillute disinfectant.
The pet dishes are washed in the dishwasher - I have no qualms about that, the dishwasher gets hot enough that I'm satisifed it does a good job.
As for transference of bacteria through contact - we do not prepare food on surfaces in this house without wiping the surfaces with a cloth rinsed in hot water and some surface spray (usually containing bleach). That isn't because we feed raw - that's because we have six cats, some of whom wander across the kitchen counters when they feel like it. Whether they were fed raw or kibble, counter wiping is automatic before food preparation.
You're right that a novice may not realise that you need to observe hygiene when preparing raw meals or raw feeding your cat or dog, but I wonder whether there is any need for greater precautions in terms of what your raw fed pet comes in contact with - even kibble fed cats walk across the sofa and the counter with the same paws they scrabble about in the litter tray with. If you can manage that, why not manage raw feeding?
To lolo62, try starting your cat with a single raw chicken neck for its evening meal. Be prepared, she may 'kill' it all over again, throwing it around the place and so on. As per the above conversation, you'll need to clean up the space she's in after she's done that. You can hit the neck with a hammer to make it more easy for her to eat (observing usual hygiene precautions). If she'll eat a chicken neck, that means she'll eat raw bone (often the most difficult part of the raw diet - plenty of cats will chew raw meat strips but won't touch bone). If she'll eat bone, you can consider moving to a raw diet (hygiene aspects taken into consideration). That could be a raw, fresh chicken neck every morning (one a day), and for her evening meal, some chunks of raw meat (never mince, they need the chewing action) and twice to three times a week, a small piece of raw liver (a 1.5 inch cube or thereabouts).
In terms of how much meat, based on cubes - about 1.5 inch cubes, the kind you'd use cooking a beef stew - try three cubes for one meal. If she won't eat them all, try two cubes. If she's begging for more, push it to four cubes. If you're still feeding kibble, half that down - one to two cubes of meat for a meal.
I find a number of benefits from feeding raw - but I can't feed all raw, because my cats just will not tackle raw chicken necks. They were recommended by my vet to keep their teeth clean (in fact, he insisted I try them, and when I discussed how my cats wouldn't have a bar of them he went through how long they can go without food. I fed chicken necks at every meal, morning and night, for three days, and offered nothing else, before I cracked.)
Subsequently I feed royal canin oral care sensitive for one meal, and raw meat for the other. I feed tough meat in large chunks so they absolutely have to chew and eat slowly. They get liver occasionally - twice a week maybe, a cube each. I find far less incidence of vomiting after eating (can happen from scarfing down bite-sized food like kibble or processed bits in gravy far too quickly). I also haven't seen a single hair ball in this house - not one, ever.
Give it a try, along with L-lysine on her food for a bit (try 1/3 of a 500mg tablet, sprinkled on her food morning and night for a week, so in other words she should get approximately 2/3 of 500mg each day).
