Gentle, Compassionate Care for Cats & Their Families

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.

A Cat Clinic recommends heartworm prevention for your cat

Spring is here!

As the days get longer and warmer, it’s time to think about making sure your cat is fully protected against heartworm disease.  Even if your cat does not go outside, he or she is at risk!  Feline heartworm disease is potentially fatal and cannot be treated in cats once infected.  For more information, see our blog post “Those buzzing mosquitoes are not just annoying! Feline heartworm Disease“.  Call us at 301-540-7770 or email messages@acatclinic.us to discuss options for heartworm prevention for your cat.
