Intragastric pH in 2 cats (denoted by lines connected by gray triangles or black circles, respectively) for 8 and 5 days following cessation of omeprazole therapy. The mean ± SD intragastric pH (represented by the horizontal dashed lines) from cats (n = 6) in this colony receiving placebo in a previous study was 2.0 ± 0.5.2 Note that from days 2–5, cat 1 (gray triangles) had a mean intragastric pH more acidic than a normal cat and on days 2, 5, 6, and 7 the mean pH of cat 2 (black circles) was also below 1.5. The pH capsule passed from the stomach of cat 1 on day 6, so readings past day 5 were not evaluated.
