Oh my, this little Princess
! She has her own mind, doesn't she...lol??!!
Honestly hon - I wouldn't even fret about feeding that Cesar's if it gets her to eat. I mean, if her allergies would do okay w/ it - and - if it got her to consistently eat by using some of it -- I'd use it. And then in the meantime if Cesars makes you uncomfortable, you could get some other one-off cans to sample like from Pet Club or something...?
When Marcel was sick w/ giardia as a puppy, getting him to eat could be nearly impossible. One thing he would almost
always eat was those little teensy mini hotdogs that you find in the toddler section - they come in little glass jars. I don't know how you feel about those - but I wonder if she'd like little pieces of those hotdogs on her super picky days....?
