We bought ours at Fressnapf. It was with us after 2 days.

We also had this problem a few months ago. At least Galaxus was the first dealer to deliver - but at a much higher price (CHF 198.00) than the competition. Even now, thanks to Google, you can find it for CHF 138.00. Unfortunately, delivery time is about the same vague (2-4 days) as at Galaxus.
By the way, our cats, one too heavy, one too light, and we are very happy with the part.
