Study design and timeline. The blinded study started at Day 0. Screening (examinations, owner questionnaires, bloodwork, fitting the cat with an activity monitor) occurred 2 weeks (14 days) prior to Day 0. Cats were examined in the clinic, and owners completed assessments at Day 0 and Day 42. Owners visited the clinic alone to complete assessments on Day 21. Treatment period 1 (T1) was over days 0–21 (3 weeks); treatment period 2 (T2) was over days 22–42 (3 weeks).
