Does anyone here own a hedgehog tenrec(s)?
How intelligent are they if so?

I've read from a few publications that the brains of tenrecs most closely resemble the brains of Mesozoic mammals, and that they also have cloacas despite being placentals. I was wondering if tenrec intelligence could be indicative of Mesozoic mammal intelligence, and if so how intelligent (or unintelligent) they are from the experience of those who handle(d) them.

As someone who's only seen videos of them, it does seem like there's a lot less going on behind their eyes than other small mammals, but that's just me. I'd be interested to hear from those who have actually known them.

Also, what are the chances of keratin spines having evolved on mammals during the Mesozoic? What would their chances of fossilization be if they existed? I wonder due to them having evolved separately on both tenrecs (who themselves appear more primitive) and hedgehogs.
