There are countless varieties of bowls to choose from such as stainless steel, plastic, stoneware. However, plastic bowls are easily scratched and can harbor harmful bacteria. Double dishes, one for food and the other for water are also not a good idea. Food can get into the water dish and make it distasteful for your cat to drink. Dishes that are somewhat flat can help keep your cat’s whiskers clean. You can have automatic feeders and bowls that allow you to control the number of days to feed automatically. There are raised bowls. Then you have automatic waterers and fountains. Some kitties love to drink flowing water and cat water fountains provide the opportunity. You can personalize your cat’s bowls and purchase colors to match your decor. Whichever you choose, be sure it is safe for kitty and remember to provide fresh water and check food for freshness.
