I made sketti today as well.. with cow, no pig no dog koala nor frog :D
Yep, that's what Per did, although he usually uses chicken or turkey, which Moxie looooves. Okay, she also loves beef and pork -- for her, any meat is meowingly delicious!!! >^.^<
I agree with you on the koala - probably tastes heavily of eucalyptus which would not go at ALL with a tomato sauce.
