Cats, like humans can suffer from colds, flu and sore throats. But as they are can't tell you they're in pain, owners must look for outward signs that the cat has a sore throat, so they can seek veterinary help if required.
Watch your cat to see if he is gulping or swallowing frequently. Loud gulping sounds that happen several times throughout the day may be a sign he has a sore throat.
Observe your cat for drooling. Drooling more than usual can be a sign that the cat has sore throat and is reluctant to swallow because of the pain, or the throat is swollen and she is unable to swallow.
Feed your cat as usual. If your cat is not eating the usually amount of food or seems reluctant to eat or drink as much as usual, it could be a sign of a sore throat.
Listen to your cat’s meow and notice if it is deeper or more hoarse than usual. Like human’s voices, cats' voices can change if they have a sore throat.
