Compounded Doxycycline for Pets
In cats, dry doxycycline tablet administration causes esophageal stricture — a documented severe complication. Compounded flavored liquid suspension eliminates this risk and improves compliance.
Why Chewy Pharmacy can't fulfil this prescription
Chewy stocks commercial doxycycline tablets. There is no commercial feline-safe liquid option. For cats, this means owners either compound or risk esophageal injury.

Species-specific benefit
Critical safety issue: ISFM has published guidelines specifically warning against dry doxycycline tablets in cats. Compounded liquid is the safer form for chlamydiosis, Mycoplasma, and Bartonella treatment.
Avian chlamydiosis treatment requires 21–45 days of daily dosing at 25–50 mg/kg. Compounded avian-strength liquid is the practical form.
