my kitty cat daphne is my best friend. she's 6 years old and has a lot of life left. but she's really fat. she eats a regular amount of food but is still really chubby and overweight. i dont want her to develope diabetes or anything. she doesn't excersize much and has very little interest in toys... she doesn't generally like the outdoors either. She has a very senstitive stomach, and a new diet might effect her "business" or her digestive system. i haven't talked to my vet yet... but i'd like some advice so i have an idea of where im headed with this... i really don't want anything bad to happen to my baby because I love her so much... do you have any advice about like stomach-senstitive diets i could try or excersize ideas i could use until i get her to the vet???
