Clinic Cats

Burnie ~2010 – 2012 – 2020

Burnie was a long time clinic cat, who retired Christmas 2017.  He was feeling lonely after Nylas passing, and when he went home with Heidi for a week over Christmas, the decision was made. That is he made the decision. For his final years he enjoyed being able to roam in the country and not having to live in a kennel at night. Burnie originally came to us through the Nanton Animal Protection Society after the fire of 2012. He became part of our family very quickly. We missed having him around, but are extremely  happy that he enjoyed his final years.

Dash 1993 – 2011

Dash was our long beloved clinic cat. When she was a tiny kitten she was brought in by a RCMP officer, and he had to pull apart the dash of his cruiser in order to get her out, thus giving her name. She grew up as a clinic cat and was well loved for many years. She is missed by all.

Nyla ~2001-2017

Nyla came to us in the summer of 2014. She was having some health problems and not doing well at NAPS. After an adjustment period to life at the clinic Nyla thrived for several years before new health problems emerged. At first we could keep her healthy with medication, but eventually there was nothing more we could do for her. She is missed as Debbie’s back warmer.
