What to Actually Write Down About Your Pet's Food
The few notes about pet food and reactions that turn out to be the most useful over months, and the ones that mostly waste time.
Four notes that save the most time later
After two years of tracking my own cat I narrowed her food log to four short fields. Everything else turned out to be noise.
Date, product brand and name, reaction in a single word, energy in one number. That is it. The whole entry takes ten seconds.
- Date: useful for spotting patterns within a week of a food change.
- Product: brand plus the specific recipe, not just the brand.
- Reaction: one word is enough — great, fine, itchy, soft stool, refused.
- Energy: one to five so you can graph it over a month.
Notes that look helpful but are not
Detailed reasoning about why your pet reacted that day. You will not remember the context six months later and the reasoning is usually wrong anyway.
Long ingredient lists pasted in. The bag still has them. Your notes should be smaller than the bag, not the same size.
When the diary becomes a real tool
The point of these notes is the pattern, not any individual entry. Once you have six weeks of data, you can see things like: every food with chicken meal in the top three ingredients turned into a soft-stool week.
That is the kind of evidence a vet can act on quickly. It is also the kind of evidence you can show yourself the next time you are tempted to buy that one brand on offer.
