Kitten foaming at the mouth

One of the bottle babies is foaming at the mouth. I applied Frontline about 35 minutes ago. He is 9 wks old. Is that to young? I have done it before and never had this reaction.

If they lick it off another kitten or somehow get it in their mouths, they can start to foam, but foaming can also be a sign of poisoning. I seriously recommend that you call an emergency vet right now and talk to them about this.

Thankfully it was a false alarm. The dog must have brought in some grass because he had some grass in his mouth and was gagging on it. As soon as I removed it he was fine. Wheeew, that was scary!

still, rinse the kittnes mouth out well, there may have been pesticide or weed killer on the grass!

My Annie would slobber foam EVERY time I applied Frontline. In fact, the vet told me to possibly expect it before I used it the first time, and that it would pass in a few moments, and was not harmful. It worried me, but she never had any other adverse effects from Frontline.

Hmmm, that is interesting. I guess I will watch to see if it happens in the future. I am pretty sure it was the grass, but who really knows unless it happens again. He is fine today.

I've had this happen a few times after flea treatment was applied...I have 5 cats to treat and I try and do it now late at night when I know they will be less active and I have even done it when they are sleeping...less of a chance they will lick at it on themselves or the other cats..
