Aibu to ask what this is on my car?

[Unhappyvegan]

I've no idea. Pic 1 is it in position as found and pic 2 is it on its own. There's no wires or clips to suggest it should be attached!

Is it a tracker? Should I be worried? Is the cat going to explode?

Damn it. Pictures

I'm a bit worried by this exploding cat!

I think the cat will be fine.

Call 101. I think that's a covert car tracker.
Very worrying.

Is it a new to you car?

Is any of it magnetic? How long have you had the car?

slipperywhensparticus yes, though it was PIL previously (they've had it from new) and they haven't a clue

Has it been in the garage for anything recently? It might be something belonging to a mechanic that's been left there accidentally.

is it a lid to something?

Wasn’t there a thing a while ago where your insurance was less if your mileage/ speed etc were tracked? Or am I making that up in my imagination??

Yes, went to the garage a few weeks ago.

Not a lid, has a hole in the back through which I can see cables.

Nope cannot see the cat, is it hiding, might be a tad warm in there.

BabbleBee you aren't making that up, but pil say they didn't have one of those

Can you remove it?

Is there any kind of branding on it?

Is it loose and you’ve moved it in those photos?

Smoke detector??!!

Is it heavy?

steff13 yep. It's completely detached, no suggestion it was ever attached. No clips or glue residue etc, no wires sticking out and not a lid. No obvious branding.

Is it possible that someone wants to track your movements?

Is the red dot a light? If you can move it could you take it to an auto parts store and see if they recognize it?

flouncyfanny but should it be there? Should it be attached?

IdiotInDisguise heavier than I'd expect from its size.
