So i took my 1yr old female sibe Tia to the vets yesterday for her first booster injection, iv noticed today that her right eye has become constricted (smaller) and is slightly cloudy also, her left eye is completely normal. Shes fine in herself but it is really making me worry. Im wondering if it is anything to do with the booster injection, an allergic reaction maybe? because it seems strange that it has just happened after this. Has anybody else had a similar problem with there Sibe? Thanks
