They’ve tolerated Felidae with KMR being put in their mouths, but not chicken. Today I tried itty bits of cheese and, Bingo!, they ate them. Then I did the usual Felidae and KMR with a light dusting of grated cheese. First Pernicious (with his new green collar) caught on and kept returning and slurping more. The others were interested but didn’t want to get their faces too close. Then Perp was tempted and I just scrunched him closer so he could smell it and he started to eat.
The other two are, like, “Dude, that’s ridiculous. Where’s my bottle?” Ha ha! Their bottle days are numbered.
