I've raised £400 to Help Snuggles the street cat get the dental treatment she needs

Snuggles (That's what I call her) has been living in my garden and in other peoples garden for at least the last two years. I have knocked on every door on the street to find her owner but no one is admitting that she belongs to them :(. She seems to prefer to be an outdoor cat and I do not mind feeding her and making sure she has access to clean water. I am currently making her an outside house that she can go in if it is raining or cold.
I have cats of my own and they are not keen on letting her move in. I also have very limited funds due to other factors etc.
As you can see from the pictures her teeth are not in a good condition and this could cost £300 or more at the vets. I help out at a local cat rescue and their bill is shocking! so I can't ask them to help me out.
I just need to raise as much as I can and I will pay some myself and I am sure the other households that feel her might help too.
Please help snuggles.
