Hi Val,
For our young ones in rescue we use a product by Mycodex called Sensicare. It can be found at most vets offices as well as online. It has only a 24 hour residual and is extremely effective is treating the problem. It can also be used on their bedding and on furniture and carpets. It is non-toxic to children and other pets (except fish). I am sending you alink to a site that has it online if your vet does not carry it.

I hope this helps. Please let me know if you need additional information.
