Ack! Poor Sky - and poor KAK! What an unpleasant find!

I hope your vet has something helpful to say about the issue of getting worms even when you use flea treatment. I have had the same thing happen twice over the years! I'd love to know what the vet tells you!

The last time it happened at my house, I noticed that I did have a flea or two, in spite of the Advantage treatment applied about two weeks before the discovery. Good luck solving this unpleasant mystery!
