Adjust the food as you notice an increase or decrease in the animal's weight. Cats, as carnivores, are meant to eat infrequently and fast in between. It is not unusual for cats to refuse their regular food for several days - looking for a change in taste and texture. If your cat has been eating a certain food for a period of time and all of a sudden stops eating - this does not mean the food is wrong. Take it away for a few days and you will find that they will switch back.
Veterinarians know that crystals, along with other health concerns, are often caused by diet.
Changing food, along with antibiotics treatment is usually recommended. As improvement is noted, it is presumed that the problem must have been the food. This is not always so. Perhaps in truth, the pet owner should continue with a natural diet as the pet's system adjusts to a natural food - their system is now mostly cleansed. Flint River Ranch feels that using a food with chemical additives and low quality by-product ingredients will only create a new environment for the waste material and crystal problem to develop again over the years.
