Should you notice concerning symptoms in your cat, you will want to visit your veterinarian, who will conduct a physical examination. Your veterinarian will ask you questions in regards to the symptoms you have noticed, when you first noticed them and any changes that have occurred. You will also be asked for details in regards to his diet, medications and supplements that he takes and whether there have been any recent changes.
Depending on the physical examination, your veterinarian may conduct a complete blood count, serum chemistry analysis, urinalysis and stool sample evaluation. These will help your veterinarian determine if there is an underlying illness that is leading to your cat’s symptoms. Your veterinarian may obtain a sample of your cat’s skin cells and view them under a microscope to see if mites, fungus or bacteria may be causing your cat’s symptoms.
If your veterinarian feels that your cat is experiencing an allergy to something he is consuming, like lysine, he will work with you on developing a plan to eliminate different elements of his diet. Should your cat be taking different supplements, your veterinarian may recommend eliminating them first to see if his symptoms are resolved. You can then add them back in one at a time and see if the allergy is triggered, thereby confirming what your cat is reacting to.
