Well it seems that my female chinchilla has developed soft stools that when she tramples on them squishes. So I burnt some toast - imagine the looks when my husband sees me taking a piece of toast out of the toaster smoking

And I gave her a 1" square and she took some bites and then threw it down and walked away. So my quesiton is, I know to increase the hay, I will work on her eating the toast, what other options do I have? There has been no change in her appetite, there is no evidence of anything funky with the poop (mucous, blood, etc) Smells like poop I guess no real foul smell, and she is maintaining her weight, actually gained a few grams from a couple days ago. She's active, and if it wouldn't for me seeing the poop I wouldn't even know anything is wrong. And she's drinking normally. She did have a raisin after her weighing today, but I'm not going to give her any more until it clears up.
So what other treatment options are available - or do you think I should just stick with what I am doing and wait a little? And about how long does it take for the stool to return to normal?
