St. Louis Cat Clinic now carries Antinol for treatment of arthritis in cats. Antinol is a sea sourced Omega Fatty Acid supplement. We tried it on our 18 year old cat Veronica who was no longer responding well to Dasuquin supplements. Veronica walks much better and is not walking in a squatting position anymore. She has trotted and even run down the hallways since she has been on Antinol. Dose is one gelcap once a day for life. It will take 4-6 weeks to note improvement.
