Pre-Treatment Checklist

Pre-Treatment Instructions

Preparation: It is very important that you have read the entire Getting Started section of the website prior to your appointment. Many commonly asked questions are answered here. Methimazole and/or herbal supplements must be discontinued at least 7 days prior to treatment. Hill’s Prescription y/d must be discontinued at least 14 days prior to treatment. (Unless otherwise advised.)  We do not allow dogs inside the building.

Appointment: Dr. Vaughan will be meeting with you and your cat at your appointment time. She will palpate your cat’s thyroid gland to determine its size. This is one of several criteria used to determine what dose of radioiodine is advised for your cat. It is important that someone that lives with the cat and is aware of their medical history accompanies the cat. We will be able to keep your cat to administer the treatment the same day.

Food: Your cat will be hospitalized for as little as one night up to 10 days. Since many cats are particular about what they eat, you are welcome to bring their favorite food(s).  No fasting needed.

Personal belongings: bedding, toys, and other personal items cannot accompany your cat into the nuclear medicine ward. Your cat must be in a pet carrier when you arrive.

Medications: If your cat is taking any medication, we will be happy to continue to administer that while they are in our care. Please bring each medication in its original container.

Payment: Is due at the time of admission. We accept all major credit cards including Care Credit. Cash is okay. Checks are not accepted.

Cancellations: As we routinely maintain a waiting list, we do need 48 hours notice for any cancellations or changes.

Location: We suggest using Google Maps to get directions. These are also on our website. Please note the Shoreline location is not near Lynnwood on Highway 99.  We are located in King County on Aurora and we share a building with Cats Exclusive Veterinary Center for which you will see a large orange sign.

Thank you for letting us take care of your feline friend

I wanted to drop you and everyone at FHTC a note to let you know that Byron (the PAWS’ kitty FHTC treated pro bono earlier this year) was adopted last month! Even better, he was adopted with another senior, all-black kitty we had in care.... read more »
