Pets

Our cats have never tried to claw their way out of soft carriers. Not that they were thrilled, but it's way better than the hard carriers. He (just the one, now) can barely stand up in it. He's sitting or lying all the time anyway, except when stress-excreting (all three ways, like clockwork). Because the soft carrier has both top and end zipper openings, I am able to reach in and remove one of the layers of absorbent pads I put in before the trip. Awkward, yes, but he settles down quickly.

I've looked into cat strollers. For him, going to the vet is so stressful that I'd want to have a different stroller so he won't think he's going to the vet all the time. Also, the visibility in those is much better than in a regular soft carrier.
