Urgently looking to rehome this sweet boi

EDIT: So many people DMed with interest and I'm so extremely grateful. Taking him to his new family today, found through this thread, with some other wonderful people on reserve to catch him just in case it falls through. Thank you so much for loving this fella at first sight!!! I never ever wanted to be this person, as I know so many kitties need homes. That's why I took in this guy recently, when an acquaintance needed to rehome him, because I didn't want him on the street or worse. However, my resident cat is now refusing to eat from the stress of it all, to the point that she's visibly weak. Syringe feeding her atm but that's going as well as you'd expect with a cat 🥲 I know cat intros can take time, and even though they're in separate rooms, Resident Cat is on a hunger strike. Syringe feeding her isn't sustainable and I can't get nearly enough in her. She's as stubborn as she is picky about food. I can't bribe her to eat with Churus, salmon, chicken, tuna, nutritional yeast, cheese, milk, butter, or yogurt. New Cat is about 1, neutered, has all vaccines. Vet visit last week says he's a healthy boy. Anxious but extremely sweet. Loves chicken Churus and headbutting you with the force of a truck. I'm already frantically reaching out to shelters but so many are at capacity. Thanks just for reading this.
