What’s the best way to store wet cat food?

Store unopened wet cat food cans in a cool, dry indoor cupboard away from sunlight and heat, following the storage label. After opening, cover the food and refrigerate at 40°F or below (about 4°C), then follow the product’s after-opening time limit. Hill’s gives 5-7 days for its products; another brand may require a shorter period. Discard any food left in the bowl within 1-4 hours, depending on your brand’s directions and room temperature (Hill's Pet storage tips; I and love and you sit‑out guidance).

The FDA’s pet-food handling advice is to cover and promptly refrigerate leftover canned or pouched food, keep the fridge at 40°F or below, and wash feeding utensils after each use. Do not leave the whole opened can out while a serving warms.

Unopened cans: where and how to store them

• Keep cans indoors in a controlled environment, not in a garage or outdoors where temperatures and humidity fluctuate (Hill's Pet storage tips).
• Use a cool, dry shelf away from direct sun and heat sources, within the manufacturer’s storage limits (Hill's Pet storage tips).
• Do not freeze canned food before opening; freezing can change texture and taste (Hill's Pet storage tips).
• Use the date stamped on the can as your best-before guide, and rotate stock so the oldest cans are used first (Hill's Pet storage tips).

After opening: simple, safe storage steps

Cover, chill, label

1. Cover the can tightly with a fitted pet-food lid or plastic wrap to reduce air exposure and moisture loss (Hill's Pet storage tips).
2. Refrigerate immediately and keep between 40°F or below (about 4°C) (the FDA’s recommended maximum). Use the contents within the label’s time limit; Hill’s gives 5-7 days for its products, but that is not a rule for every wet food (Hill's Pet storage tips).
3. Write the open date on the lid so you do not exceed the safe-use window.

Portion smart and serve at room temperature

• Dish out only what your cat will likely finish in one sitting.
• Most cats prefer food at room temperature; you can gently warm a portion by letting it rest a few minutes or placing the sealed portion in a bag and running warm water over it briefly (I and love and you sit‑out guidance).

Serving safety: how long can wet food sit out?

Follow your brand’s specific directions. As examples from manufacturers:

• Up to 4 hours at room temperature above 50°F before discarding, per Hill’s (Hill's Pet storage tips).
• 1-2 hours indoors at room temperature, per I and love and you (I and love and you sit‑out guidance).

In warmer rooms, aim for the shorter end of the range. Wash bowls daily to keep feeding areas clean and appealing (Hill's Pet storage tips). For simple cleaning options, see our guide: What should you wash cat bowls with?

When to throw it out

• Uneaten food that has been out beyond your brand’s advised time.
• Food showing off-odors, visible mold, or unusual discoloration or texture changes (I and love and you sit‑out guidance).

Freezing and warming: what manufacturers say

• Do not freeze canned pet food; manufacturers note it can alter texture and palatability (Hill's Pet storage tips).
• To serve chilled leftovers, let the portion warm slightly on the counter or warm it briefly in a sealed bag under warm water so it’s not cold from the fridge (I and love and you sit‑out guidance).

• Mark the open date and your product’s use-within deadline
• Serve small portions and discard leftovers within the brand’s time window
• Wash bowls and utensils with hot, soapy water after each use
