Roxy is going to take some work. She's the hold out. There is always one. lol
Usually if she doesn't care for a particular food... she will sit next to her food dish... and stare at me. I'll say to her..."That's all there is. That's lunch." After a few minutes of pouting, she will eat.
This food... she voiced her opinion...loudly last night. I sprinkled Vets Best on it... she licked off the Vet's Best. She did get some food in her, so I didn't worry (too much) about her not eating an entire meal.
Breakfast was a food she likes.
Lunch: Weruva and By Nature Organic Chicken mixed together, just a little bit. If I mix too much, the results are the same as if only the "icky" food is on her plate. Anyway, she did her best to pick out the good food, but she did end up eating quite a bit of Weruva.
I'll feed it as part of one meal, a few days in a row. Eventually she will get used to it, and like it...going by past experience.
The other 5... LOVE it.
