I've found these methods helpful in obtaining urine samples from ferrets: Use No-Sorb Litter, available from your veterinarian. Use Aquarium Rocks (available from Wal-Mart or anyplace that sells aquarium supplies); just rinse them thoroughly first Then, take a 10 or 12 ML syringe and draw up any urine that is left in the box. Please consult your doctor regarding the amount of time that the urine can be stored safely before urinalysis. :) kim www.pooflinger.com Home of the Spahn Ranch Ferrets [Posted in FML issue 3602]
