So for background on my cat: I’m in college but still live at home with my mom which means this is also where my cat lives. We have had him for about 16 years since he was a kitten, my parents are divorced but he has always stayed with my mom. He’s got this stomach thing so he’s prone to throwing up if you feed him wrong but he rarely does now (every now and then he’ll have a really bad week and it’s an issue) but he’s had this for 90% of the time we’ve had him at the least. He also does normal cat things like being in birds and other small animals occasionally. Also he’s terrified of other people/animals. 

My mom hates him, and much prefers her dog (that attacks me for trying to walk him. Every night. For the past 6 years... and she’s done nothing about... but that’s another thing) and while I’m gone visiting my dad in another state for 5 days she wants to board my. He is terrified of other people/animals and I feel that this is going to be unnecessarily stressful for him and it’s a waists of money that they (my mom and grandma) want me to pay for (that’s another post). She doesn’t want to deal with him and has said as much. But he’s really simple. If he’s being annoying just feed him and if he doesn’t want food check that the pet door is open and if it is just pet him for a few minutes and he’ll be fine. She doesn’t interact with him because she hates that he vomits and brings in dead things which is normal for cats. And she’s lived with him for 16 years. AITA for not wanting her to board him?
