Kirsten!!! In a way this is a blessing in disguise that it was discovered so early!! My vet has said that some cats do not show renal disease until 75% of the kidneys function is gone!! However, Luna is so lucky to have a Mom like you that will do what she can to take care of her girl!!! If this is of any help, Raven was ONLY 4 years old when she developed kidney disease. Now, after eating a kidney diet(k/d canned) and fluids for a few years, she turned 11 in April!!! Prayers for both Luna and you!!! Sandra
