I've even scrambled my cat eggs with cheese when he didn't want to eat his canned food ! Too, we had a Scottie and each time she went out to do her business she got a treat when she came in.....didn't matter what it was, sometimes I would give her a saltine cracker...she ate it.....THEN she got where when of us went out (not to do our business but to take trash out, to garage, etc.) when we came back in she thought she still needed a treat !
My SIL has a Maltese and he won't eat until the food is pre warmed....I dog sat with him for a week and sure enough, he wouldn't eat until I warmed the food..the little stinker !
We had another cat that would only eat canned food mixed with dry food...couldn't be left over either; had to be fresh and mixed together.
That is what makes them special and we have to be special to put up with some of their tactics !
