So mother bought some bones from the butchers today, (>.>

no doubt I was pretty upset (near tears at the thought) & I guess; hysterical. Anyway she told me they're already dead, & of course I explained that she was just supporting the industry by buying it (& the workers were looking at me like I was crazy)... anyway it ended up in me saying I was disappointed and hurt by her so I asked her 'why' and she said they "add flavour".
Bottom line, I was wondering, are there any such thing as "mock bones" (I know, I highly doubt it) I could use or something to add flavour? I'm not sure if it's the actual bulkiness of the bones or just the flavour itself... I suggested tofu, but she didn't buy it. I don't think any mock meat will work because she assures me that she "won't get the meat". Is there anything out there like that?
I think this is the last excuse for her, so if I can replace this, she'll have no excuses left.
Please & thank you.
