Cats are Conservatives

How do I know? My husband recently found a LARGE bag of cat food on sale for $10. That's less than twice what I pay for the usual fare when it isn't on sale in a much smaller bag, so he bought it. They ate the cheap food the first night out of extreme hunger (I was home late from work, exhausted, and had forgotten to pick it up). They haven't touched it since. The birds will eat it, but the cats won't.

Cats do not like change. They adore routines- if you feed them at the same time every day, go out to the garden at the same times, sit down to pet them at certain times, they will love you for it. Change the routine and they will announce their annoyance in no uncertain terms. A lot of times the language is nonverbal: staring with disgust at the food bowl, turning a back to you when you go out to pet them, keeping distant instead of coming to you for a scratch behind the ears. 

I hope they adjust and eat the new stuff, or they'll have to eat the birds for a while (and thus indirectly eat the cheap stuff) until we use it up.
