pet weight for in-cabin flight

[grey_dreams]

I've booked a KLM flight from Amsterdam to Chicago for the end of May. My two dogs are confirmed in the cargo hold and my cat is confirmed for in-cabin. They have an in-cabin weight limit of 6 kg for the cat+carrier. I've just come from the vet, and my cat weighs 6.3 kg! She's put on a lot of weight, but I really hadn't realized she was so heavy.

Does anyone know how strict they are with the weight?

She will be in a soft-sided carrier that will meet their limit of total size of 115 cm (WxHxL).

I'm starting her on a diet today! Not sure if we will make the target in 6 weeks!

Help!

Thanks in advance.

Your check-in procedure depends on the representative at the counter at the time, and we do understand that weight is important on international flights. How much does your carrier weigh?

Thank you for your reply. I haven't bought the carrier yet, but it will probably be about 1.3 kg. So she would have to weigh less than 5 kg

There is a hand-baggage limit of 12 kg. I wonder if they would let me do a trade-off? I have to pay 200 EUR for my cat anyway, she is not counted as hand-baggage, but as special cargo. They told me that I can still have another piece of carry-on hand-luggage. I've never seen them weighing people's hand luggage either.
