Has something happened to Friskies canned cat food ? Our cats used to eat it all the time, but reject it now.

12. My cat won't eat anything that has been out of a can for more than an hour or two.

Both the dog and the cat are fussy eaters though.

Tricked them both, gave the cat dog food and the dog cat food.
Smiles all round.

But pet diet preferences do change with age, our old dog now eats mashed up tin stuff, with some water added.
Bit of stock cube mixed in for smell/flavour. Bit of a warming up in the microwave.
Now on 4 small meals a day, after weeks of gastric problems - drooling and vomiting - doing better on some vet provided medication. Steroidal anti- inflammatory drugs and pain killers.
Only $850 for that visit, blood tests and X-rays - good news, no cancer though.

It would be the lack of preservatives that allows changes in the smell and color once exposed to the air that turn the cat off in your case.
