Our cat who is turning 12 yrs old has caught sometype of cold, he has been sneezing with a runny nose, for the last 4 days, well the other nite is eye was really sealed shut, and looked infected the next morning it looked like it has cleared up and he seems more active and comes to watch T.V. with us, but now there is a yellow stuff that has came out of the same eye, he is still eating and drinking, should I take him to a vet for eye drops or does anyone have a idea what i can get him to help is eye, and cold? And do u think the cat caught the same cold that my daughter and I have had, because the cat started to get sick when we did???
