Hi all. I have a semi feral girl who I cannot handle or pet, so I can't brush her at all. She is long haired and occasionally gets the longest hairballs I have ever seen. I am worried for her because she does have a ton of fluffy fur but being unable to brush her im not sure what else I can do to help avoid a potentially dangerous situation with these hairballs. Has anyone had success with a specific type of hairball remedy?
