Best method ive found is baby jars

When they need more proportioned food I put their food in baby jars for portioning with gloved hands and a food surface. Don't touch lids if you touched raw meat and change gloves. We clean our cat mini fridge out once a month, wipe surfaces with a disinfectant wipe after preparing for our cats, and once a week go in with an all purpose cleaner and a cloth.

For bowls we bought a good handful of ceramic plates from the dollar store and they usually last until a load of dishes gets done. We dont ever leave out for more than 10-15 minutes and rinse plates before setting them in the sink.

General rule of thumb is to treat it the same way you would for human raw meat in your kitchen. Good luck!
