Entering Animals as Assets

I have seen multiple questions but no answers that apply to our situation. We have a business that imports/exports and breeds reptiles. How do we enter breeders we purchase as an asset? Similar to other questions I have seen, there is no asset choice that animals fall under. We are an LLC, so it isn't a hobby. We are not a farm so it doesn't fall into the farming and breeding. Last year we simply expensed them and included them as inventory but are thinking we need to not include our breeders in inventory anymore. Any help is appreciated.
