So, you should feed your cat a diet that has a controlled amount of magnesium. There are many nonprescription cat foods for urinary cats that have optimum magnesium levels to maintain the right pH in the urinary tract.

Age Group

Not all cat foods are suitable for all age groups. While younger cats need cat foods that are rich in fat, older ones do not need so much fat as they are prone to getting obese.

So, when you buy cat food for a cat with urinary infections, make sure that you buy it according to their age.

Otherwise, you might end up creating other health problems for your pet friend. It is best to get guidance from a vet on this.

Prescription or no Prescription?

How much food does my cat need?

This depends on your cat’s age and how much physical activity your cat does in a day. If your cat is young and always running around, they will need more calories, so you need to buy cat food with a high-calorie count.

However, if your cat is older, you should feed them twice a day. Since older cats do not do much physical activity, they tend to get obese if fed excessively.

Why is magnesium present in cat foods?

Even though high magnesium levels lead to the formation of urinary crystals, magnesium is an important part of your pet’s diet. An optimal concentration of magnesium is needed for proper muscle function, bone health, heart health, and other things in your pet’s body.
Cat foods that are made for urinary health do not completely lack magnesium. They have a controlled amount of the mineral since your cat will always need this mineral, even if it is in a limited amount.

What if my cat does not drink a lot of water?

If your cat does not drink a lot of water, this is something to worry about as a lack of water intake leads to urinary tract problems such as kidney stones and crystals. You can try to make things interesting by using a cat fountain. Your cat might drink more water this way.
Alternatively, you can try to feed your cat more wet food as it contains moisture. Even if you are feeding dry cat food, you can use wet food toppers to fulfill the moisture requirements.

Will my cat get bored with his food?

Can I get cat food for urinary crystals without a prescription?

If you do not have a vet’s note, you can buy nonprescription cat food for urinary crystals as they are also easily available.

Why does my cat pass urinary crystals?

The main reason for this is a shortage of water in your cat’s body. The waste material that is excreted from the cat’s body needs to be diluted with water to be passed as a liquid. When there is not a lot of water content in the cat’s body, the urine is passed as crystals.

Now, there can be many reasons for this. Your cat might have a urinary tract infection, kidney stones, backbone issues, or any major health problem. To know the cause, you should get your pet checked by a vet before the problem gets any worse.

Are vitamins important for my cat’s health?
