Spiders are about the exact opposite of aerodynamic. Not that Nepeta takes any sort offense at being bombarded by by fake spiders. She's had worse things coming at her, and even if she hadn't, she's not the sort to be terribly bothered by most things.

"It's alright. It hasn't hurt anybody. They're only spiders, after all."

That said, she bends down to pick up the spider, and if she's using her mouth to do it well, that probably has a lot to do with the fact that she was raised by a cat, even if hooves being awkward to hold things with doesn't hurt either.
