It's hard to know quite what to say right now. I'm so very sorry that Ralph will be going to the Rainbow Bridge, often the right thing to do is the hardest to do. Hugs and prayers on the way for you.
Happy birthday, Ralph! Have a super day full of love, treats, and lots of that yummy cheesecake.
Happy birthday, Norton! Hope you have a dynamite birthday that brings you lots of love, treats, and all the things a sweet kitty like you deserves. Enjoy your cheesecake!!
