Tigger hates tuna, and all other people-food, but tonight she actually decided she wanted to eat some after I gave Willow some

Does the fact that Tigger's decided she wants some food that she literally hates, mean she's going to die soon?

She's always thought of people-food as being stinkies and nasties and pulls faces about her meowmy eating any of it - "what are you trying to feed yourself, meowmy? that's a stinky!" the same sort of face that would get pulled if a really stinky fart was to be let off in a enclosed area, everyone wafting the smell away from themselfs, thats the type of reaction Tigger does to people-food

but cause tonight she wanted to eat actual tuna its left me terrified the fact she asked for some tuna means she's dying
