I feel bad for separating my cat with my aunt
I've been living with my aunt for the past few months. My cat came with me and he absolutely THRIVED. Previously he was surrounded by cats and dogs and he hated it. He's 100% people kitty, not cat kitty.
They grew a bond together, I can see that my aunt is obsessed with him (which is understandable, he is such a needy, cuddly monster).
I moved a week ago and I have serious difficulties deciding whether I should take him or not. I've already postponed moving him and I intend to do that this week. He went through a lot when he was little, he almost passed away. Due to that he has a recurring runny nose (and it doesn't bother him much, different vets say it's okay and it would just happen), he has to eat low fat food (and he's sometimes like "well no, actually I don't intend to eat THAT anymore" and I have to look for different food) etc. I'm just super worried that his needs won't be met with my aunt.
She's unable to deep clean his litter, can't give him any meds, can't take him to the vet. She can handle my short term absence, but I'm worried she wouldn't be able to manage without me visiting frequently. I will visit her regardless, but I have a lot on my plate rn and I don't think I can just drop everything and run to her if something happens.
I'm also worried that yet another move would be stressful for him (though the last time wasn't as stressful as I thought it would be).
Other than that, I love both my kitty and aunt to death and want them to be happy. She can talk about him all the time, how he gave her a kiss, how he sleeps funny on her lap and it's disheartening to think that I want to take it from her. I can hear the sadness in her voice when talking about him moving. But at the same time I also feel like we have a special bond with this little panther, he helped me go through a lot.
I can't find her another cat, because if something happens I would have to take it and my kitty would bully another cat.
I don't know what should I do. I feel like a monster for taking him and honestly want to cry, but at the same time I think it's for the best? But maybe it's not that big of a deal and he could easily stay?
