Our one cat had a cold a few weeks ago.... now she's getting better but the other cat has what seems to be a mild cold. I really thought she was getting better today but a few minutes ago she let out a moan and then vomitted on the floor by her litter box (one large puddle, with two smaller puddles). Eyes are bright, she's loving, and right afterward she ate treats and did that little paw thing on my shoes. Anything to worry about?
