If I read your post correctly, you still live in your mother's house and depend on her to feed Bella several days a week when you work late and you will need her to take care of Bella for ten days when you go on vacation. If so, you really aren't able to fully take care of Bella as you say so you will have to compromise.
You need to respect the fact that the smell of canned food makes her nauseous. Remember, she is doing you a favor by feeding Bella for you when you are not there to feed her yourself.
Get some Innova kibble as Ashley V said so your mother can feed Bella that when you are working late or on vacation. I'm sure Bella will do fine. |
