The smell has totally gone so I managed to finish today.

I stuck the heatmats down with insulation tape, with a couple of layers of kitchen foil underneath to reflect the heat upwards.



The slate is only placed onto the base, not sealed in.



Zuki and Zulu were very excited about their new home and are busily exploring every corner. (Probably checking if I have closed all holes or if there's a chance of escape, lol )
