I find it easier to just leave the carriers out for a while after each use (like a week) and open so they treat them like the boxes. Never had a cat hate a carrier since.

I had to switch to Jerboa because Connect kept glitching out on a bunch of posts where it would load the image for a second, then just give a blank screen. So you’d need to either keep clicking out and reloading to hope it worked, or load externally in a browser.
