When appetite changes: notes that can help your veterinarian
Contact your veterinary team about a new appetite concern; use these notes to explain what changed.

Do not wait for a completed food diary before asking for veterinary advice. A change in appetite deserves a conversation about the individual animal, not an online guess about pickiness. If your pet appears seriously unwell, seek urgent veterinary help rather than working through this page.
Field notes
- Contact comes before the worksheet.
- Separate food offered from food eaten.
- Keep uncertain amounts clearly uncertain.
- Follow the clinic’s individual instructions.
01Lead with the concern you have now
Start the call with the animal’s species and the change you noticed. Say whether you have seen other changes, but do not use the absence of a listed symptom as proof that waiting is safe.
You can say: “My ___ is eating differently from usual. I first noticed ___. I am concerned because ___. What should I do now?” You do not need a diagnosis to ask that question.
02Distinguish the bowl from the animal
Describe what was offered and what you directly saw the animal eat. A bowl emptied in a multi-pet home does not identify who ate from it.
Use the information already available: food name ___; offered at ___; eating actually seen ___; leftover amount, if known ___. Avoid turning a rough impression into a measured total or repeatedly offering foods to test a theory.
03Put events in a simple order
Tell the clinic when you first noticed the change and what was happening around that time. Note a food change, treatment, journey or household event without claiming that it caused the appetite change.
A short sequence is enough. If another carer has an earlier observation, identify who saw it and when; two separate accounts are more honest than an invented single timeline.
04Make relevant items identifiable
Have food packaging, the current treatment list and previous clinic instructions available if easy to reach. Explain any possible access to an unfamiliar food, medicine or other substance.
Do not force feeding, start a fasting experiment or add a medicine based on this article. Ask the veterinary team what information and immediate actions are appropriate for this animal.
05Record the response, not an online deadline
Write the clinic’s advice, the person you spoke with and the contact or visit arrangement. Read back anything unclear, including what you should report if circumstances change.
If the situation changes while you are arranging care, tell the team. This page provides no number of hours that makes an appetite change safe to watch, and you should not postpone contact to make the record look complete.
Questions to take with you
Ask before deciding
- What should we do now for this animal?
- Which existing food or treatment information should we bring?
- How should we contact you if the situation changes?
An appetite note cannot assess severity or diagnose a cause. Veterinary instructions take priority over record keeping.
