Greetings,

My sister goes on holidays next week and gives me her cat. Poor little thing was sick (thyroid) and lost a lot of weight. As a sibling, it's my duty to give my sister a hard time, so what can I do to fatten up her cat? She loves fish pasta and tuna once a month; any more and she is like meh. Any recommendations for what cats like so I can say, "Don't know what your problem is, little sis; guess the cat loves me more than you"?

Thanks in advance.

Update : Thank you all for your advice. To clarify, the cat is old, 19 years, and the vet stated it's okay to let her eat what she wants because of her age. She lived with me before, so my sister doesn't have to worry about her being alone.
