Buffalo- Jeffery hated it, the other two went nuts
Tilapia- Unanimously loved
Bacon- Jeffery spit his out, Gyarados played with his for fifteen minutes before nomming and Ariel inhaled hers.
Turkey- Everyone was pretty Meh.
Now granted, these occurrences were very few and far between. The bacon thing was possibly fueled by cold meds ("I can taste my bacon today!... Jeffery would you like bacon?") and will never be done again.The same thing with the Turkey. However the buffalo is something I'll continue during those rare occasions when I treat myself to bison meat, and my roommate cooks a lot of fish so she's always sure to pinch off a small bit and give some to everyone for dinner before she throws it in the pan.
They also get chicken from time to time, and bits of raw steak, however their main diet is always 2 pellets twice a day. They tend to get any kind of meat (usually chicken or fish) only once a week. It does give them some variety, which they all seem to enjoy.
