About a year ago my 8 yr old cat had one runny eye - clear liquid didn't really look infected.Took to vets and vet examined eye and said no sign of damage, would be an infection, it would spread to other eye and to put cream in both...managed to get cream on both eyes once and bad eye maybe twice ...didn't like it very much and eye was improving so decided not to traumatise her anymore ...and it got better.Now she has the same thing again - one runny eye, the same eye - has had for almost a week now and other eye not affected. Have given it the odd wipe with cooled boiled water. Eyelid looks a bit puffy - and discharge is clear. She does fight sometimes and wondering if it is a trauma thing. Or?Does anyone have any idea what this could be?Her vaccinations are up to date.(I know she should really go to the vets - and if she really has to go she can - just rather she had a bit of a break . She had a gut obstruction in the summer and a major operation. When I took her for vaccinations in November she was really freaked out. This happened before when she had an infected tail and the vet had to squeeze it - freaked out a month or so later - but didn't have to go again till her next vaccinations and she was fine - think she must have forgotten!)
