“Food was left out” is not the same as knowing the cat ate.
The care plan should define normal intake, presentation, timing, individual confirmation, medication dependence, and the point at which reduced eating or drinking requires action.

Normal baseline
Food type, amount, timing, preferred dish, location, warming, water, treats, eating speed, and ordinary leftovers.
Meal presentation
Refrigeration, warming, moisture, supplements, mixing, fresh portions, automatic feeders, and how long food remains available.
Individual confirmation
Separate rooms, direct observation, microchip feeders, cameras, or another method in multi-cat homes.
Medication dependence
Whether food must be confirmed before insulin or medication and what the approved response is to partial or absent intake.
Nausea and vomiting
Approach-and-retreat, lip licking, drooling, repeated swallowing, vomiting, food aversion, and the need for veterinary contact.
Hydration context
Water source, fountain, bowl level, wet food, urination, vomiting, diarrhea, kidney disease, and signs outside the normal pattern.

Vague instructions create delayed decisions.
State the normal amount and the minimum acceptable intake, how many meals may be missed, whether treats count, what vomiting changes the plan, and whom the sitter should contact.
Appetite-vulnerable cats may need closer observation or supported care.
A cat who has stopped eating during previous absences, requires supported feeding, needs food before insulin, or can deteriorate quickly may be safer in feline-only boarding or veterinary care.
Prior stress anorexia
The cat has a known history of refusing food during travel, boarding, visitor care, or environmental change.
Medication or insulin depends on intake
The care plan requires real-time decisions that cannot wait until the next scheduled visit.
Supported feeding required
The cat needs hands-on food presentation, hydration support, or repeated reassessment across the day.
How can the sitter know a shy cat ate?
Use portioned food, separate feeding, cameras, microchip feeders, known patterns, direct observation when possible, and a plan for when evidence remains uncertain.
Does eating treats count?
Only if the guardian and veterinarian define how treats relate to the minimum acceptable intake and any medication or insulin decision.
What if the cat eats less but seems normal?
Follow the agreed threshold and timeline. Cats can appear quiet or “normal” while intake is declining, so the written plan should not depend on appearance alone.
Can the sitter syringe-feed?
Only under an explicitly reviewed, veterinarian-directed, safe plan. Supported feeding can be stressful and carries risks that should not be improvised.
Document exact food, amount, presentation, individual confirmation, and escalation.
Update the portal whenever diet, appetite, medication, nausea, kidney disease, diabetes, feeding equipment, or household dynamics change.
