I was on my laptop and I had a thumdrive next to me, Joel came up and grabbed it so I went to go get it from him and ofcourse he ran downstairs with it, but I couldn't find it

So im not completly sure he swallowed it, but im still worried.
To make it any better it was a tiny thumdrive, and my sister said he should be fine even if he did swallow it, so will he pass it or should I take him to the vets?
