Urinary issues are a common problem for cats. Bacterial infections may accompany other lower urinary tracts problems (FLUTD), such as urine crystals or uroliths (bladder stones). While these issues are treatable, they can be painful. Untreated, they can actually be deadly.
Why Are Cats Prone to Urine Crystals and Bladder Stones?
Urine crystals and bladder stones form when there is more magnesium, calcium, phosphorus, or protein in the urine than can be dissolved. Special diets which prevent the formation of one kind of crystal can actually cause the other, so it is best to avoid such diets for your cat.
A great deal of research has been on-going as to the relationship of diet to urinary tract health, and the thinking has changed over a period of just a few years. Originally it was thought that diets high in magnesium and ash contributed to the problem. Now, more emphasis is being placed on the pH of urine (acidic or alkaline). Veterinarians recommend a range between 6.0 and 6.5.
Which Foods Will Help Prevent Urinary Problems for My Cat?
By far the most important "food" for your cat's urinary health is plain water. That's because neither crystals nor bladder stones can form when minerals are sufficiently diluted.
It can be tough to get your cat to drink a great deal of water, as cats are naturally thirst-tolerant animals. Some strategies for increasing your cat's water intake include purchasing a "kitty fountain" or providing plenty of fresh water in multiple bowls. Kitty fountains are particularly effective because many cats prefer drinking running water.
In general, good quality canned cat foods are better for urinary health than dry foods. That said, however, there are some dry foods that have been carefully pH balanced. Even if you choose a high-quality dry food, however, canned food and water remain your cat's most important weapons against urinary crystals or stones.
Which Foods Should I Buy For My Cat?
While you may prefer to buy organic or specialty cat foods, it really isn't necessary unless your cat already has urinary issues or your vet suggests a particular type of food. Generally, a good quality commercial food should be fine for your cat. Do avoid fish flavored foods, which are said to be suspect in crystal formation.
If you do prefer to serve your cat dry food (as many people do to avoid the smell of canned options!), it's is still a good idea to supplement your cat's dry food diet with a small amount of canned food each day, also avoiding the fish flavors.
Make sure your cat always has plenty of fresh, clean water, and avoid feeding him table scraps. If you find that your cat is not drinking enough, try experimenting with a kitty fountain, changing his water daily, or adding more water bowls to your home.
Watch carefully for any signs of distress, such as straining to urinate or missing the litterbox.
