Help cat with cold, conjunctivitis and two broken ribs

Hi

Two weeks ago I've found in my yard cat you can see on the photo. His name is Koń (English for horse)

Koń had some accident and overall was in bad shape. I've taken him to the vet and started his treatment. Vet told me, that Koń has cold, conjunctivitis and two broken ribs. Whole treatment cost would oscillate around 700€. I was able to pay 400, but due to coronavirus outbreak I'm very tight on cash (my employer doesn't have money to give us full payments)

If you could help me raise 300€ left, that would be awesome - I really don't have anywhere to get the money atm.
