Help!! Cat wont leave her stitches alone

[Newernewist]

My 5 yr old female card was neutered last Monday 26th Oct
She will not tolerate a collar, I mean literally she pulls it off in seconds, the collar is the standard cheap Elizabethan collar the vet gave us.
I put it on twice, she pulled it off.
We took her back to the vets, they put it back on, she pulled it off within minutes in the carry box thing in he car
I've bought a dog jumper type thing, she got out of it in seconds, a post surgery vest like a baby gro, she played dead and wasnt happy, it didnt cover the stitches any way.
She's biting at the scab, she wasn't really bothered with it until it started that stage of the healing
I've also bought a feliway plug in.

What can I do, I've emailed the vet pictures as they requested a week after they did a physical check, but ive not heard back

Any tips on what I can do to stop her.

You could try putting her in some extra large tubi grip enough to cover her middle leaving legs exposed? If it’s healed enough she may just wash the scab and not actually reopen it. But you would have to watch her like a hawk and see how much grooming she does to the wound.
I confess to being a bad cat mum and let mine get in with it - they only went as far as they ‘hurt’ themselves iyswim with grooming and then they stopped and left it alone. No ill effects or stitches pulled etc. But I may have just been lucky.

Tubigrip was one of my thoughts, it just needs covering up somehow
Shes not constantly at it, just when it scabs.
My other cat done at the same time has totally left hers alone

I have had another thought. What about a piece cut from a pair of old leggings? That would make a soft, yet grippy tube to slide over her and onto her middle.

Probably not helpful but, my dcat did this I tried 2 different collars and a babygro thing, she slipped out of all of them. In the end I just had to leave her to it and she just stopped bitting at her wound. She had made it bleed and removed the scab at this point. Not sure if it was because I left her alone but she just stopped. Wound was fine at check up. My older cat didn't even have a collar/gro as it was not the done thing and I had no problems. I wonder if we do too much with cats these days. Good luck.
