Kirsten, I've also spent lots of money on vet bills,surgeries, and tests but it's all worth it in the end to get the unconditional love that my cats give me. My parents will never understand so I rarely ever let them know what's going on with my cats. They only know about Storm's PU surgery and Starr's surgical biopsy along with his colitis and food allergy problems. I know that you'll do what's best for Luna to help keep her healthy and happy. You always have the support of PT behind you.
