Dear Lily, what a beautiful Tortie girl you are. Your face is so sweet with those green eyes and your pink tongue. I bet this picture was taken after you had some treats. And you know exactly how to get your mom to hand over those treats.
I'm sorry about your heart murmur. It does not slow you down though, and you're even taking care of your kitten sibling. Whenever you have to take a break, your family is there to cuddle with you.
Lily, you are indeed such a lovely girl. You deserve a great celebration today with your family, and I hope you all will be together for many more years.
