sounds like an allergic reaction.

Not normally, but your cat may be having a serious allergic reaction to the Clavamox. Call your Vet immediately!!

p.s. If they didn’t tell you how to administer the Clavamox, just put the amount they said into the syringe, hold your cat in the crook of your arm, insert syringe through the SIDE of the mouth and point backwards. Make sure the head is not tilted all the way up as they can aspirate it into their lungs. Just at a little lifted angle is okay.

p.s. If there is medicine that spills over on his face, just use a warm, damp guaze or cotton ball to clean that off. But this does sound like an allergic reaction. I would stop the Clavamox immediately and call the Vet, like, now! If they aren’t open where you are now, take your cat to an emergency vet that is open after hours. Highly recommend this in case it’s a case of Anaphylactic shock.

“Anaphylactic shock, the most severe type of anaphylaxis, occurs when an allergic response triggers a quick release from mast cells of large quantities of immunological mediators (histamines, prostaglandins, leukotrienes) leading to systemic vasodilation (associated with a sudden drop in blood pressure) and edema of bronchial mucosa (resulting in bronchoconstriction and difficulty breathing). Anaphylactic shock can lead to death in a matter of minutes if left untreated.”
