It's been some time now since Adaptil brought out their new Adaptil diffusers - they apparently have refills that last up to 60 days and they work at a lower temperature, so are even safer than the old ones.
However, I can never find where you can get them from! I thought at first they just weren't out everywhere yet, but it's been a few months now and still everyone is selling the old diffusers....!
Does anyone know where you can get the new ones, or why they aren't in the shops/online?
If anyone isn't sure of the differences, here's a comparison between new and old - the new ones look quite different and the refills are not compatible between new and old:
