how long can you leave wet food out?
shellgg posted:
My cats like to go back to the wet food throughout the day? Is it
safe to leave it in their bowls all day long?
Also, how long does an un-opened can stay good in the fridge?
Violets_are_Blue responded:
Wet food should be disposed of after about 20-30 minutes. It has a tendency to grow bacteria after a bit which can cause illness.

Opened cans are usually okay for about 3 days after opened as long as they are covered when not in use and refrigerated at all other times.

You can usually leave canned cat food out all day without problems. It will also stay good in the refrigerator for several days. The more important point is how long will they eat it? My own cats like their food fresh and won't touch it after several hours. And forget about if it's cold from the 'fridge!

Thank you! My cat will drink the juices and leave the rest. So I pour a bit of water over the left overs and tell him it is more gravy. And at some point later, he drinks and eats it. We do this all morning. By evening he wants no more of it and we start all over again. Sometimes, he sleeps past the gravy add ons, and later in the afternoon resumes his leftovers. We have done this for years, he is a reformed feral and is now 10, and a total delight. He is finicky about his food and will not eat what he does not want ( whatever was on sale) I appreciate your answer allot!!

Had to chime in here because my cats do the same thing! I thought I'd be nice and buy those cans that are for "gravy lovers" but they still just slurp up the juice and leave the rest.

And you're right! Forget about it if it's cold. Or even warmed up in the microwave. They know and they're not buying it. LOL
