Interesting the rock tips stuff... Despite it claiming to being 'different' I suspect it's some flavour of superglue.

Question: What's in Rock-Tips?

Answer:
Rock-Tips is formulated around a non-toxic yet very powerful medical adhesive. We've added additional polymers for strength and flexibility, which gives Rock-Tips  it’s ‘skin-like’ feel – like a real callus.

So it's superglue with just enough stuff added to brand it differently, one suspects.

Indeed. A quick google shows that superglue rebranded and re-jigged is commonly used for wounds on cats...
