Hi there, I have two domestic short hair cats. One male and one female. The female cat always seems to have eye gunk every day. Which normally is fine, as its like what we humans have in the mornings. You know the dried up stuff in the corner of your eye, or its like erm stringy bogey type before it dries. Thats all ok i guess. But recently the female cat has got these brown stains in that corner of her eye. Its like she either rubbed the stuff into her fur, or like she’s had some powder in her eye and her tears are bringing this browns stuff out.. Does it seem like she has an eye infection? Im pretty sure she hasn’t like breathed at a bag of cement as they are rescue cats and are afraid of everyone apart from my family. So when they go outside they only sit on the fence or hang around in our gardens right next to us for 20 mins tops (or until someone comes out). But none of the gardens have any powdered substance like cement bags in there. So the next thing im thinking is the litter tray.... we use the Otto stuff from lidl. They seem to like it the best. They hate catsan or the weird stoney stuff and don’t seem to like the paper stuff. Sometimes from this litter stuff there is fine powder at the bottom which is also this weird browny grey. She’s about 4.5 years old (human years) Umm i think thats all the info i can think of. What do you think? Does she need a trip to the vets or just monitoring?
