My baby is too skinny I have a 6 year old girl. She’s extremely active during playtime. Very nimble and can jump high. An indoor cat only.

She is bony. Weighs no more than 6-7 lbs. whereas my boy cat weighs 14 lbs (can’t be as athletic as her). But because she’s so frail and bony it concerns me. She does eat. Maybe not enough. Loved raw pieces in Science Diet dry food. Loves treats the most. Loves wet food (we try to give her a can by  herself in a separate room a week to have to herself). Loves dairy. Kinda picky with eating dry plain pellets of food.

Due to her weight, she is cold and frigid all the time. We sleep together and she’s finally understanding how nice it is to be under the covers.

What can I do to keep weight on her?
