I got some pepsid (actually it was the store generic) 10 mg. Our Vet suggested it a while back but we tried changing food and a few other things first to see if it was an allergy to something. In any event, my husband thought I said he could have 1/2 of the 10 mg. pill and that is what he gave him. I have been reading posts only to find that everyone is giving 1/4 of the 10 mg. pill. Should I be concerned? Some people are dispensing 1/4 pill twice a day so the dosage amount is the same, but will it hurt him to have it all at one time. We have 3 other cats and their hard cat food stays out all day so there's no way to plan on giving his pill before he eats. He seems to eat little bits all day long. Thanks for any input.
