So we got the blood test report for Vita. All is fine!

This makes me nuts. Sparkle and Vita are both losing weight and we don't know why. Sparkle is now eating 5 times per day, while the rest eat 3 times. (She had been on 3 meals per day.) Blood tests and urinalysis all look fine on both cats. The vet suggested feeding them both some canned food once per day.

So I guess this is good news. Just puzzling!
