✓ Safe storage protects flavour and reduces bacterial contamination
✓ Refrigerate covered wet food promptly, seal dry food in its original bag inside a container and wash utensils.
✓ Discard food with swelling, mould, unusual smell or contamination; illness after eating needs veterinary advice.
Safe storage protects flavour and reduces bacterial contamination. Wet and dry foods have different storage needs and the manufacturer's label should guide timing.
The short answer
Safe storage protects flavour and reduces bacterial contamination. Wet and dry foods have different storage needs and the manufacturer's label should guide timing.
What to observe first
Compare the moment with your cat’s usual pattern. Note timing, frequency, body language, appetite, litter-box use, mobility and any recent household change.
Why the setting matters
Wet and dry foods have different storage needs and the manufacturer's label should guide timing. One isolated detail rarely explains behaviour or health on its own, so look at the whole cat and the immediate environment.
What you can do
Refrigerate covered wet food promptly, seal dry food in its original bag inside a container and wash utensils.
A gentle way to test it
Make one small safe adjustment and give the cat time and choice. Avoid punishment, forced handling and several changes at once, because they make the response harder to understand.
When to contact a veterinarian
Discard food with swelling, mould, unusual smell or contamination; illness after eating needs veterinary advice.
Prepare useful information
Write down when it began and how often it occurs. A short video, clear photo, food record or litter record can help a veterinary professional assess a pattern that may not appear during the appointment.
Store wet and dry food differently
Transfer an opened wet-food portion to a covered food-safe container or cover the can and refrigerate it promptly. Keep dry food in the original bag, tightly closed inside a pest-proof container, so the lot number and storage barrier are preserved. Avoid warm, damp cupboards.

Serve safely after storage
Use clean hands and utensils, wash bowls between wet meals and serve only what the cat is likely to eat while fresh. Discard food with mould, swelling, an unusual smell, damaged packaging or prolonged room-temperature exposure. Contact a veterinarian if illness follows eating.
