I used to buy tin cat food from the groceries in different flavours ranging
from fish to meat to vegie varieties. She is slowly eating less and less of it
and I said to myself maybe its because the tinned food is bad (outdated, old,
etc) then I tried an expensive brand and she ate it all up like its the first
time she's eating! Now, she's again turning her nose away from the regualr cat
food. Does that mean I'm stuck with expensive brands now? That shows you how
smart these cats are.

Maybe its the turkey. :P

Nitrates can be used on meats to make them look and smell fresh (to
us). When cats scent nitrates, they don´t eat the meat. It is ilegal
to put nitrates on meat but you never know.

Maybe it was on sale because it was close the the expiration date and they
could smell or taste the difference. I buy my crew deli turkey about every
other week and they gooble it up. If I have boneless chicken breasts I dice
one up for them and they love that. However, I have stopped using onion when
cooking the chicken because it is bad for them. Am I trained or what?
