Sorry to hear one of or both the E's have got worms. At least it can be treated easily - I expect! Which kind of worms are they? The long white ones should be easy to spot - they seem to grow out of their behind as if they've been fertilised.

For how long will they need the treatment? I know you're about to travel, so I hope they only need one dose, or the person who look after them can get the rest down their throats!

Good luck!!
