I've raised £500 to help fund vet bills and necessities for a lost/abandoned kitten in the West Norwood/Dulwich area

Over the weekend, I visit my family as always. This weekend we spent outside as the weather has been amazing, now there are a lot of neighbourhood cats around whom I am familiar with, but i kept noticing a much smaller cat about 6 months old, one i have never seen before, he seemes so under nourished, but yet so playful and sweet. Throughout the day I had seen this kitten a fee times just going about its day and on several occasions seemed to have had some problems with the locals cats. As the kitten was so friendly i was able to catch him and take him home, hes the sweetest kitten ever and appears nothing but grateful for the turn of tables, although on a small budget myself I have managed to feed him and take care of him so far. It is apparant to me that he needs a trip to the vet as he seems to have some kind of reflux problem when eating and only drinks very little amounts and I am extremley concerned. He also needs vaccinations and to be nututred, im guessing as hes not been nututred hes probably never been to a vet.
Hes at home with me now, I have called him Feline, I want to keep him as he brings a joy to me day but I will only be able to do so if I can afford the vet bills, otherwise unfortunately I will have to take him to the RSPCA
