i feel like she's starting to look like she needs to eat now.. she's looking a little triangular and the skin is a bit looser.. not drastic but it's been over a month and i'm just really worried. how do i know when it's time to take her to the vet? or should i try live before i take her to the vet? or is feeding her live (considering her lack of interest/fear of the f/t food) a really risky idea?
