Baby ferret diahhrea after changing food

I bought a Marshall ferret which seemed happy and healthy and still is except I changed his food over to Wysong Epigen 90 digestive support. He has had diahhrea ever since. Obviously he can't continue to eat this stuff. Should I charge him back to the Marshalls diet or try something else?

Thanks,
Billy

Hello and Welcome to the forum! When you switch food did you switch all at once or slowly? Whenever changing food it’s better to add a little of the new food and then less and less of the old until it’s all new food.

I mixed is slowly but he should be used to it by now.  What are some other good foods?

I use the Wysong Epigen regular mixed with Go Fit & Free cat. You can try giving your baby a little bit of canned pure pumpkin to firm up poo. Make sure it’s the pure pumpkin and not pumpkin that already has spices in it. I’ve used it and even mixed it in the soupy.

When I had my ferret when I was a kid we fed him kitten food. I read so many things in the internet and I don't know what is a good food?

We got our last ferret from a private breeder. The Wysong Epigen and Go Fit & Free is what she told us to get. Plus his soupy is freeze dried raw chicken. I get it all online from chewy.com

In addition, she is not that sort of expert whose only knowledge comes from books and lectures. She has practiced what she preaches on https://www.worldofdiets.com/diet-solution-program-review/. As Isabel was once overweight and suffered from all sorts of health problems, she has tried many dietary approaches over the years. As many of us experience, all of these diets failed miserably. It was only when Isabel set out to find a solution herself that she was able to find a real way to shed off the pounds and become much healthier.
