Honestly please do not get a dog Emma.
You’ve been told walking is a cure for your cancer and you can’t even manage that. She wouldn’t take a dog out on a nice day let alone when it’s cold, dark and rainy! You can’t do it for your own life but you’ll do it for the dog right? And you love being a crazy cat lady, why bring a dog into it not knowing how the cats will react?
Oh yeah because you only think about yourself and what you want!
I genuinely think she wants a dog because all her cats dislike her and she thinks a dog will just love her back, just like how WLS is a magical surgery that requires no effort apart from the surgery itself.
