Hi, I am the proud owner of 3 beautiful cats. My oldest is 14 years old. My 2 boys are 1 year old. The two boys get along really well. They play a little rough at times. I noticed yesterday that one of the boys has problems with his right eye. The eyelid is a little swollen and red. I assume his eye got hurt during one of their play fights. His eye is only slightly watery. Is there anything I can do for his eye? I do have some vetropolycin eye ointment. Can I use this on his eye? TIA.
