Is this like a one-time question, or is it a repeatable question? Cause my cat has a habit of randomly screaming and most of the time it's nothing and very occasionally it's a medical issue (she has chronic illnesses). I'd love to have a repeatable "Where does it hurt?"
That's a great question. I want to say it's just a one-time question to make it more challenging. I'm almost tearing up thinking of your kitty meowing and you gently asking her "Where does it hurt, baby?"
Okay then. I'm assuming she'll be able to understand my question in it's entirety:
I want you to know that your mom [my sister] and your sibling cats all loved you very, very much, and that you're a good cat, and it's nothing you ever did that made them leave you behind, [they're all dead now] and I also need you to know that the yucky-tasting-thing is really really good for you and keeps you healthy and I'm sorry it tastes weird, and if you're feeling bad it'd be incredibly useful if you could point your tail at the thing that hurts, and I'm glad you're a part of my life and I love you very very much too, okay?
My heart goes out to you and your cat, sounds like you two have been through a lot. Your kitty is lucky to have you and loves you, even though you have to give her the yucky thing.
