is Calvan young, and then perhaps he got older and thought hey enough of this? or was it a new flavor that Calvan was ready to fight for?
with my cats, Patches and Charlie were always the piggies, gobbling up their food and then going after the others, and they were the youngest of the group! but they have learned their manners, now when I feed them, they patiently wait til a plate is put in front of them! I guess they just had to 'grow up" for their manners to kick in? LOL anyway one time, I fed them turkey, and I guess Emma decided this was her very favorite, because SHE ate all hers and then hogged up everyone elses!
