My Jasmine did the exact same thing when I switched her to Innova Evo a couple of months ago. She's eight and had been eating Iams her whole life, so I was very precise in mixing 1 part Evo to 3 parts Iams in her first dish. I intended to transfer her very carefully and slowly, but nope, not happening! *smile* Jasmine picked every single kibble out of her dish, spread them all on the floor and then ate only the Evo. *laugh*
These guys are so smart! So funny!
