14 year old coco needs full extraction of her teeth

Hi my name is Emma. A few weeks ago myself and my husband found a little black poorly cat with blood and pus coming out of its mouth. We took this poor baby to our local vets for pets in Taunton somerset. I asked if I could check in everyday to see how it is. Found out that she has been missing for 5 years! Vets for pets contacted the owner but unfortunately the owner can no longer have her. We also found out she is a girl, her name is coco and she's 14 years old! The vets have looked after coco and tried to make her mouth better but unfortunately all her teeth are so badly rotten and she's still in alot of pain and barley eating the only thing left to do is a full teeth extraction so she can then be pain free. Iv asked if I could adopt her as soon as she is well enough after her surgery and give this beautiful senior girl all the love in the world in her twilight years. If anybody could help with funds towards her surgery me and coco would be eternally greatful. Thankyou for reading xx
