I've been a cat mom since I was born. My mom used to feed all the strays and turned me into cat woman. Right now, I have two kitties - both are not mine per-say; my boys adopted them and I'm a granny ( who coughs up the litter and food expenses but draws the line at the vet ones. They were told it is an expense that is part and parcel with being a parent)
One is so fussy with his food; he will gobble up something one day and turn his nose up the next. The other will eat anything that placed under his nose - plus the snubbed bits from his bro! Then he ends up chucking it all up - conveniently on the plate!
Ironically, whatever one snubs we switch to the other ( before the barfing, I might add) and it's eaten. They're fussy little fuckers!!
