Advice needed on poorly cat please

[CatsCantFlyFast]

Will try and keep this short. At lunchtime today my youngest cat was sick, which was mostly liquid and fur. It has happened on the odd occasion in the past so I wasn't worried. However this evening he has pooed out a long piece of twisted cling film or tape. This seemed to traumatise him as it got stuck in his bum while he hurtled around the house, clearly scared that it was 'chasing' him. Anyway it dislodged itself and I cleaned up and left him in peace... It had clearly frightened him. Just went to check on him now (2 hours later) and found more tape hanging from his bum - I got it out (don't ask) and have brought him downstairs for a cuddle. He is now hiding in his bed. Should I assume he has been ill due to foreign objects he has eaten, and is just traumatised and still feeling a bit poorly so leave him in peace tonight and monitor him? Or should I be rushing him to the vets?
Worth pointing out he is an indoor cat, and he ate his dinner (after the sick incident and before the poo incident)

Can you identify what it was that he pigged? (I'm wondering whether he could have still more of it inside.)

I'd ring the vet, they will have a nurse on duty who can advise you.

I think it was cling film. He's eating treats.
Will try the vet now
