I thought everyone knew about cat food can covers until I saw my sister-in-law using a ziploc baggie every time she gave her cat food. I had some covers left over from Rags (now that I have two cats, I don't need can covers because they both eat the full can together), so I gave her those.
Cat food can covers by ORE Pet are sold in sets of two . They are made of silicone, can be used safely in the dishwasher, measure four inches in diameter in a non-stretched state, have a matte finish, and because of the flexibility of silicone fit three standard cat food can sizes. These cat products come in a cute paw shape that will endear them to any feline enthusiast; they also come in a variety of colors: black/grey, orange/cream, green/yellow green, and blue/light blue.
One problem that many cat owners run into is preserving their canned cat food once it has been opened – it rapidly spoils upon exposure to air, and simply pushing the metal lid back down over the food does not create a good seal (nor does using a ziploc baggie). This is where ORE Pet’s cat food can covers come in. As was mentioned above, the cover can be stretched to fit three standard cat food can sizes, creating an airtight seal around the can that allows the food to retain its quality for a longer period of time. These cat products have an average five star rating on Amazon, and if you look through the customer comments, you will note that this product has a loyal following of satisfied customers.
