Pet's info: Cat | Mixed Breed | Male | neutered | 2 years old | 10 lbs
My cat had a hoarse voice yesterday morning and last night he totally lost it. A lovely doctor here suggested L-lysine and said it’s a mild case of URI. I was worried so observed him all night and noticed he was sneezing a little, breathing through his mouth. Slept more than usual. No runny nose or watery eyes. I thought he was gagging sometimes but maybe that’s how cats cough. Should I give him lysine and see if he gets better or consult the vet immediately?
