Our anxious cat had her teeth removed (feline resorption) and we noticed she was much bolder while she was on gabapentin to recover from the dental surgery. We talked to the vet and he put her on a daily dose of it. We experimented to find the smallest amount that gave her Courage without making her sleepy. (Having her painful teeth out helped a lot too, but it wasn’t her whole problem.) Now for normal days she gets 25 mixed into one can of food and spread throughout the day, but for a recent airplane trip she had 75 in one small meal before being put in her carrier.
