I have a 2 1/2 year old nuetered male. Tubby has had "tears" in his eyes off and on since yesterday (Thursday 11/1). Are they really tears or does he have a health problem? He seems to be okay otherwise. Although, he did sleep more today than ussual. A little more history would be: we also have a 10 year old spayed female, who is healthy except for a heart murmer. We have a 6 month old, as yet unspayed female, who is being treated for worms for the 2nd time. She has also been treated for a urinary tract infection and ear mites.All three kitties are strictly indoor cats and only go out for trips to the dreaded vets office. Is Tubby's problem reason for concern? I appreciate any help. Thank yo.
