I've raised £200 to help to fund Fudges emergency vet bill

This is our beautiful girl Fudge, she has never had any health problems, she is chipped and neautured and is as fit as any other cat her age. Fudge is 2 years old.
Our problems started 2 months ago when a couple of Tom cats kept entering our garden in wait for her and would pounce as soon as they saw her. Fudge would try her best to see the toms off but it would usually end in a fight! She got bitten on the leg which resulted in a trip to the vets and a unexpected £170 bill and a swollen back leg and not being able to walk for a few days. She regained full health.
Recently was her last trauma, an attack on her eye! This left Fudge with no vision atall out of her eye, a large swelling above her eye which resulted in the eyelid itself and her third eyelid to cover her whole eye with huge swelling. We rushed her to the vet and were given a check up, antibiotics,trauma shot and Painkillers at another cost of £120.
The swelling went down, her eye opened back up and we thought yes shes better.....until this morning.... her eye is buldging again and after advice from her vet, we need to go back in and have her eye flushed out to check inside to see if theres trauma to her eye inside and not just above her eye, this is going to cost in excess of £200.
£200 of which we haven't got at this moment in time. We can't leave it because it would get to the point where she could potentially lose her eye.
If we cannot fund this money, we will have to consider to pass her over to the RSPCA so she can get the care she truly deserves. Our insurance wont pay out due to it being another eye injury which they classed as ongoing.
Any help will be so much appreciated.
We love Fudge and shes a lovely cat who is suffering due to unspayed tom cats 😔
