KLM's cabin tops out at 8 kg combined in a 46 cm carrier — Nala wouldn't make it, but plenty of dogs and cats do. The 15-week minimum age is stricter than most carriers, so puppies and kittens out of that window have to wait for the next flight.

KLM Royal Dutch Airlines's pet policy splits into cabin and cargo. This page summarizes the weight limits, fees, brachycephalic-breed restrictions, and carrier specifications for both modes — sourced from the airline's official pet pages.

Frequently asked

What if my flight is delayed past my health certificate validity?
If the certificate window expires before you board, you'll need a re-issue. Build a 1-2 day buffer between the cert date and departure to absorb minor delays.
What happens if I forget a document?
At the destination airport: at best, an extended inspection while you produce backup; at worst, the pet is held in quarantine or returned to origin at your cost. Bring printed copies.
KLM and Air France share the same checklist — the soft carrier dimensions are the gating item. Drop your pet's measurements into your plan and you'll know within seconds whether cabin or hold is on the menu.
