Erin sounds like she has a lot of fight left in her. Has she been diagnosed with a heart condition?

I will admit I still, to this day, miss my cat Scooter for twice a day for eight years I gave him sub-q fluids to treat his kidney disease. He would gladly crawl up into my lap, curl up and purr away as the fluids raced through is line and under his skin. He was such a joy and a true gift that touched my heart deeply. I hope you and Erin have similar success and many years together (Scooter was my best buddy for 17 years).
