sudden refusal of a particular food
See if any of you can give me a take on this. I always feed Friskies Prime Filets chicken and gravy to 2 of my cats, and they suck it down like they have seen food in 8 days rather than 8 hours. Yesterday morning both of them just picked at it. Thought maybe they had found something else to eat and didn't think anything about it. Yesterday evening, still wouldn't eat it. More than willing to eat something else--gulped a can of fancy feast and ate their usual treats. This morning, I made sure that I picked a can from a different batch. Both the first 2 cans were the same lot number, Rudi wouldn't touch it and Sophie just picked at it.
I"m at a loss. Have my cats suddenly become finicky? I put them on it in the first place because they were overweight and the vet promised that the wet would pull the weight off. It did and they have thrived for several years on the stuff. I thought maybe there was something wrong with one of the batches, but since they refused the one with a diff expiration, now I really don't know what to do.
