An abandoned cat that I rescued was showing signs of a cat cold constantly even though he was current with all of his vaccines. When I asked how he could be sick the veterinarian informed me that the vaccines were like the human flu vaccines being that it did not protect you from all strains of the virus.
We were told that our cat may be sick from household stress and was advised to buy the Feliway products for our home and the veterinarian suggestions to give our cat Viralys L-lysine supplement to boost his immune system. After doing everything that we were asked our cat still had cold symptoms which included the feline herpes virus, coughing, sneezing and eye drainage.

Our veterinarian was certain that these symptoms were coming on due to the stress of being abandoned, rescued and living indoors. They noted that it was common to have sick cats in multiple cat homes where there were also dogs and any changes to a cat's life could cause the cat to get colds due to the stress.
I can understand that BUT my cats and dogs all got along and normally when one cat is sick they all are and none of my other cats had symptoms of cold or another feline virus.
When none of the other cats got cold like symptoms I thought that what my cat may have is food allergies. So I changed the cat's food to Natural Balance limited ingredients duck flavor because if a cat is allergic to food then you should stay away from chicken, beef, grain, gluten, egg and seafood including salmon as these foods will trigger allergies symptoms.
After feeding the limited ingredients duck cat food for a week I noticed that the cats cold like symptoms went away. I am certain that the food I was feeding my cat was causing him to have an allergic reaction.
