I have two young cats, Harvey is 5 months and Oscar is 19 months. Harvey started showing signs of illness, runny left eye, which then spread/started in the right eye. That led to a runny nose, blocked nose and sneezing a lot. My house is covered in Harvey snot. I took Harvey to the vets for a checkup, but the vet couldn't confirm his condition. Harvey has had all his vaccinations, so it isn't cat flu. He has had eye drops (Isathal 10mg, 1 drop twice a day), Powder we have to put in his food (Bisolvon, 1 pinch to food daily) and Metacam (2kg dose daily). Harvey has been taking the medication for over 2 weeks, but his symptoms don't seem to be improving much. About a week ago as we brought Harvey back from the checkup with the vet, Oscar started showing symptoms. Oscar started getting runny/crusty eyes. So we took him to the vets and he's now on the eye drops (Isathal 10mg). Both cats have the same symptoms, runny crusty eyes. Oscar doesn't have a blocked nose and sneezing. They haven't lost their appetite, still eating (very healthy appetite), they play all the time, they both have regular bowel movements (they pooh like monsters). Apart from the visual signs of illness, you would never think they are sick? Can anyone suggest what to do? We've taken them to the Vets 4 times and have spent a small fortune on medication which doesn't seem to be improving their condition? Thank You.
