Appetite and weight: record the direction

Make a useful weight record

Choose a consistent scale and units and note the date. Ask your vet how often to weigh your cat and whether your method is suitable. Muscle loss can matter even when total weight changes little, so examination and body condition assessment still matter. Do not treat the log as a diagnosis.

Describe what was eaten

Separate food offered from food eaten. Note the food name, texture and any treats, food stealing or competition. A cat who approaches the bowl but turns away may be uncomfortable; a cat eating normally can still lose weight. Both observations help the vet.

Avoid a food experiment during illness

Do not force a sudden change or start calorie restriction because of an age label. Ask about diet changes when other conditions are present. If your cat refuses food or seems ill, contact the clinic promptly rather than waiting for the next monthly record. Home feeding changes do not replace an assessment.
