Help fund my Kitty!

I'm 25 years old and disabled. One of my few loves in life are cats. I currently have two rescue cats, but I recently fell in love with a rag doll boy. He'll be ready in 5 weeks time, but he costs £300, while I have the money to care for the cat, to get him neautered ect. I lack the initial fees.    I'm unable to work, so earning £300 before then is really hard. I do work as a freelance artist, but again, work is hard to come by. I'm hoping I can get money for extras for him(new toys, blankets, vet bills) ect with that money.  I'm pretty unsure about this whole crowdfunding/donation thing, I've never done it before. But I'd apriecate the donations to help me bring him home.
