Ever heard of Kitty can saver? It’s an innovative, adjustable lid that has different circumference rings that will fit different sized cans. It was originally designed to keep pet food fresh in the fridge, however it works equally well to keep several other canned foods such as Tuna fresh.
When canned foods are opened, we usually seal the tin with either foil, cling rap, another container cover or even the old can cover. This may not be the best option as air enters the can thus reducing it’s freshness.
Whilst the kitty can saver was made to keep pet food fresh, it can work wonders when used for this purpose.

Please never leave unused food in a can! Not a good idea.
