Mia just turned 15. She's older but no less feisty. She's also currently living with cancer. 

We've decided not to treat it. She also has a heart condition, and with the advice of our vet, we're going to just do a wait-and-see.  With her age and other health ailments, we don't want to put her through any major treatment. She's not in pain, and she's still a good eater. She gets a little exercise, and she's still happy, so we're just letting her live her best life--with cancer. It sounds scary, but when you see her, you just know she's okay. She gets regular check-ups at the vet, and they monitor her health very closely. So, for now, I'm just keeping her comfortable and happy.

That being said, I'm not sure what I'll do when she's gone, so I'm just trying to enjoy and appreciate every day I have with her.
