They don't eat Cheerios or bread. They get maybe a 1/2 cup of pellets. And most of them end up on the floor because they like to play with them more than eat them. They do get the store treats once in a while. They are just "healty". That's what the vet said when I took them to get their nails clipped. She was pleased at how "healthy" they were. I asked were they too big...weighing in at 10lbs and 8 1/2 lbs. She said no and they were still growing. They are getting lazy. They don't even try to impress me with tricks anymore...they just want what they want when they want it and will nudge your feet or nibble to get your attention. MY BABIES !! Love them dearly. Whish you were here to pet sit. I am so concerned about leaving them for 2 weeks.
