Snip--Cinderblock is eight years old and currently resides at Northshore Veterinary Hospital in Bellingham, Wash. where she's been given, literally, a new life. CNN reports that Cinderblock's previous owner couldn't care for the cat anymore due to health issues and brought the cat in to be euthanized.Oct 27, 2019
Snip--Many people have wondered why Northshore is subjecting Cinder to the underwater treadmill. Cinder has arthritis in multiple joints and is carrying an extra 10 lb of body weight. The water provides a reduced weight-bearing environment that increases functional use of limbs without marked weight loading and resultant discomfort to joints. She's still in the process of becoming acclimated to this treadmill and the water level is lower than we would like just so she can become used to the process.
