Worried About Leaving My Cat Alone For One Night Out

[Treacle71]

It’s Diwali season and the big day for those who celebrate is tomorrow (I live in a heavily populated Asian town). 
In June, I booked a night out to see a show (I’d no idea it was Diwali back then when I booked). It starts at 7.30pm and their fireworks start at anytime from 5pm to late, round my way. I’m worried about leaving my cat for about 5 hours on his own. I’ve never left him alone with fireworks before. He usually just stays upstairs when anything like this goes on knowing I'm just downstairs. What can I do to add any comfort for him in my absence?
TIA.

Is your mother going with you?

[Treacle71]

Nope, Naomi.  She's not in town currently.

As long as the cat is indoors he should be ok. He'll tuck himself away somewhere.

Thanks, Naomi xx

I am not a cat owner and don't claim to be knowledgeable in feline matters, but can a vet prescribe some sort of sedative/calming?

How is he in his cat travel basket?

Put his basket out, cover it with a blanket and give him some cat nip.

He will be fine.

He hates his carrier, DDIL, but I'll leave catnip around for him upstairs?

You could hire a pet sitter for the evening.

Leave a radio or TV on.

^Good thinking.  We do that for our dogs when we go out.

TV on downstairs (incase he changes a habit of a lifetime and comes down) and radio upstairs. With any luck it will mask the noise.
