Am i in the wrong??

Hai! Jam here, and I really wanted to talk about something cause idk it's been bothering me lately.

Recently, I got a kitten, a stray one. Ofc this means it has worms and wtv else. I didn't get it, it was actually my mom who kittennapped him only because he was smaller than the others and probably the easiest to grab. Now I love animals very much, I'm very maternal when it comes to small baby animals because I want to care for them as much as I can (even though I don't have a job, a stable income, or even a proper things to keep certain animals). Now because of my fear of this kitten dying was eating at me every single day cause my mom wasn't doing anything. She wanted me to feed it tuna fish from the can which I said no to. She fed him milk, human milk, which they're not allowed to have. SO I asked my bfs mom for help until I can get my own money. Thank God my bfs mom loves animals as well cause she helped me get a dewormer and kitten food/formula to feed this kitten. The first time I saw him, I wanted to give him up for adoption to find a better home but ik my mom wasn't going to let me. And now, he's all that I can ever want. He's an orange/ginger male kitten who is very playful and very chaotic. Me and my bf decided with the name Kam "Miso" Cattebo, after the football player, Cam Skattebo! I call him miso thou cause that's what he's learned. Now here's the part that's been bothering me, my mom keeps trying to take credit/control over the kitten even though she hasn't put work into the kitten, hasn't spent a lot of time with the kitten, doesn't feed him every day, doesn't change his litter, doesn't go out of her own way to buy food/important things that the kitten needs unless I force her. Hell even last week she complained to me about spending only 85 dollars on cleaning supplies which we didn't have at all. Now back to the topic, she's been trying to name him Chase, cause they found him near the chase Bank. Ima be so fr, that name is so stupid and too human for him. My reasoning with his name is because he tried drinking my miso soup. And also cause the football player he's named after is SUPER energetic and chaotic which it fits. And tbh atp and even my bfs family has said this, he's my cat/kitten. Mostly because I've been spending the most time, feeding him, changing his litter, playing with him, letting him get used to my other 2 cats, getting the dewormer as quickly as possible, getting him stuff since this is a urgent and more. My mom has barely done nothing like that. And tbh idk whether or not to feel guilty about it because I mean I didn't want this kitten at all and now since I've spent time, I actually want him for him rather because he's just a cute baby animal.
