@AliciaBytes@kitten yeah, I'm no expert, but I'm pretty sure that shork-cat distance is far exceeding international safety standards!
If I'm not mistaken, this is described in IKEA-303.735.88, chapter 3 - Safety and Compliance, subsection 3-1-20. The appendix should also contain a table with all the maximum allowable distances.
In case you don't have access to this standard, it's worth checking if your national standards body has an equivalent norm, which is often the case!
