I am concerned about a few things.
1- What kind of dye is used for the chew treats?
2- Has the pecan wood been aged? I am not even sure of its safety., I can see why she would use it because it is a hardwood though. The usual chew woods for bunnies are fruit trees, willow and pine. Of course they tempt with solid oak chair legs and gnaw at solid cherry furniture as well. I'm going to do a bit more research.
OK well it seems that pecan and hazelnut are OK but walnut is not along with almond and chestnut and any red wood. I would steer clear of peach, apricot and cherry wood because some groups say that it is OK if thoroughly dry and others do not , so I just play it safe and do not use them. Of course they all need to be organic, unsprayed and untreated trees and wood, not to mention no sap!
3- Bamboo I would not consider safe as it splinters and can lodge in a bunny's mouth and not to mention wedge between the teeth.
4- The apple discs I would avoid, dried fruit contains so much more concentrated sugar than fresh, only a teeny tiny amount is OK for bunnies.
Like Moobunnay mentioned, BB here has a great shop with some awesome treats as well and you might be pleased to know that the willow treats she gets are from a lady who makes them herself as well and I know that they are all bunny safe.
Pumice I don't consider safe while its chemical structure is pretty harmless. Anything that is not digestable is a risk for a bunny as it can remain in their GI tract and cause impaction. While some may say that they will not eat that much and will just pass through, I play the safe side and besides, a bunny diet really is not in need of a pumice stone as the hay does a great job keeping the choppers filed down. I have however heard that a pumice stone works great for grooming a bunny!
