zoey seems to always be hungry!!! we feed her about 1/4c of food (thats the amount the vet told us) everyday-- she probably eats about 3 times a day. should we feed her more?! she's only 2.4 lbs at 3 mos... i feel like she is always looking for food. i dont want to make her fat... maybe i should bump the food up to 1/2c-3/4c a day? i feel like she eats when she's hungry and doesn't when she isnt-- she seems pretty smart....
