The gaps between your feeding times, and the longest fast
Enter up to six feeding times for one day. The tool sorts them, measures every gap, and shows the longest fasting stretch, the shortest gap and the difference between the two. The overnight stretch from the last meal to the first meal of the next day counts as one of the gaps, so adding all of them up should come to 24 hours, which the result checks for you. In most schedules that overnight stretch is the longest one.
No validated figure says how many hours a pet may go without food, so this tool proposes no ideal fast and no meal count. It only measures the gaps between the times you entered. How to space meals depends on age, illness and any medication, so settle that with your veterinarian. Reviewed as of October 2026.
It does not work out the amount per meal or the daily total. Use an auto feeder schedule calculator and a feeding calculator for those. This tool is for reference only and does not replace veterinary care. Contact your veterinarian right away if you notice symptoms or suspect a problem.

No. This tool handles only the gaps between times. Use an auto feeder schedule calculator for the per-meal amount and feeding times, and a feeding calculator for the daily total.
