A Cat Clinic:

A Cat Clinic has been serving the Germantown MD area, providing veterinary services to cats, since 1986.  We moved one mile west of Route 118 to our current location in 2005.  A Cat Clinic was the first veterinary hospital in Montgomery County for cats only.

MedicatioAdequan can be helpful for cats with arthritis. n update:

The medication Adequan can be very helpful for older cats with arthritis.  Several of our patients have experienced less discomfort when given regular injections with this medication.  Although it is on backorder from the manufacturer, we just received a limited supply of Adequan with a short expiration date of October, 2016.  We are offering this to clients at a 30% discount off of our usual price when purchased as an entire bottle.
