12 week old baby tree squirrel with diarrhea

[SparkysDad]

I have a 12 week old female that was doing fine and then developed diarrhea and soft stool. It does smell bad. I do not believe it is diet related as she is now weaned and has been eating mostly Mazuri rodent block with some other greens and no fruit since this started. It has been a week now. I have tried squirrel doses of Immodium for 3 days which helped a little but now that I stopped it the piles of poo are back. She was playing on a cat tree that had been outdoors for a few months. Not sure if she picked something up from that or? Not sure if this is stress related since she should probably start the pre release process or an infection. I have kept her indoors to not stress her but it continues. Has anyone had this problem as well? Maybe a parasite, is that common? Anything to try?
Thanks

Posting pics of the poo can help sometimes; color, consistency, etc can help us. How does it smell.. maybe like death warmed over, or a sweet-sickly smell? I know, gross, but like I said helpful in foguring out what is going on exactly.

At 12 weeks, they usually would not be weaned... and formula is the very best thing for them for as long as they will take it.

What "greens" have they been eating, and what is new (aside from the cat tree) that may have stressed them out? :thinking

Pr-release starts at 14 weeks or so at the earliest FWIW.
