I got it from Budget Pet Products. I was just expecting in the $20-$40 range, seeing the diffuser at the first place I looked selling for over $100 was a bit of a shock! I ended up paying about $120 for a diffuser and a spray bottle.

They say to spray it in the travel carrier, but I’m not sure how much she needs it there - now that Mr Woof’s carrier has been taken away she’s back to napping in her own again.
