So when i got Iris, she was underweight. She doesnt look too bad because of all the fur, but i was kind of shocked once i started lifting her and petting her. You can feel a lot of bones under there and she is light as a feather. She does not like or eat the cheap food her previous owners said she eats, so at first i thought thats why she is so skinny. I started feeding her a brand of kitten food that my other cat really enjoyed as a kitten in hopes she would put on some weight from it. She really liked the food and was meowing and begging for food every meal time. She doesnt however finish her bowl - ever. I weighed her after feeding her this food for about a week and a half (?) and she weighs 3,1. My other cat who is roughly the same size weighs 4,1. I waited another week after the kitten food diet plus some really delicious filéts in sauce which i could tell she really enjoyed (but still never finishes), she still weighs 3,1. Now she has also developed a weird eating issue where she sometimes wont eat unless i scoop out a few food pieces at a time and feed it to her on the ground. Anyone got any clue what to do?
