Our Facilities
Through our experience, we’ve meticulously designed our current facility to offer leading edge technology and exceptional comfort for the benefit our patients. During treatment your cat will have spacious accommodations with two separate sleeping areas. Fresh air is supplied continuously through individual vents and natural lighting is provided. In addition, comforting music and several birds are housed in the room for your cat’s entertainment.  This quiet, non-stressful environment assures that even the most timid of cats will be comfortable during his/her stay with us.

Since I-131 is a radioactive substance, safety requirements dictate that treated cats be housed in a state-licensed facility and that their radioactive waste be properly handled.  You will have the opportunity to view the area where your cat will be staying at the time of admission.  Daily phone updates will be provided, and visiting your cat can also be arranged.

The stay in our facility is just 3 nights.
