My cat (5 years old) all of a sudden looks cross-eyed. The inner lids which are normally tucked away in the inner corners of his eyes are covering almost half of each eye. His pupils are very small, even when it is not bright, and certainly much smaller than his brother's pupils.
Does anyone know what this could be? Am I being very silly or should I take him to the vet?
If it is both eyes and he is otherwise OK, it is probably a viral infection called torovirus. This virus only has two symptoms - third eyelid protrusion and diarrhoea - and they don't always have both of them. It is a good idea to get him checked over but if it is torovirus he will recover without specific treatment.
Took Archie to see the vet this morning. It is conjunctivitus (sp?) and torn 3rd eylids from being such a little scrapper! He gave him a thorough check and declared him otherwise horribly fit and healthy.
Stealthsquiggle absolutely, wagging finger, stern voice, the whole thing. Poor cat then got it parroted back at him by DD (2.5). Much better now although still not took keen on me as "evil woman with eye drops".
