Thanks, Bonkers! We've got her almost entirely on the Wellness now, with just a smear of the other on top.
As I'd said, we had an appointment, but she started eating again, and now seems fine. I'll continue to give her some pumpkin for a bit and see how she does. She'll be ticked with me(I have to syringe it- she WILL not touch it in the food

), but I can live with that!
What was concerning me was not knowing for sure how well her bowels were working. She's a very secretive girl. Hubby just happened to see her that day when she didn't know he was around the corner. But I'm assuming if she's eating and drinking fine, then everything else must be working as well!
