They are both beautiful! My cats Milly & Izzy are also mother and daughter just 1 year apart and they get along fine.
It will be easier to get them settled in to a new home together because they have each other to make them feel more secure in new surroundings.
Balinese have amazingly super soft fur, my Izzy is part Balinese and her fur is bunny soft so be sure to pet Keisha and Tippie a lot when you meet them. I think you will know if they are the right ones for you. It was hard for me when I had to say goodbye to my Samantha after 20 years and I knew it was right when I found Milly & Izzy, it took 2 of them to fill the empty spot left by Samantha. Good luck and let us know how it goes.
