Our cat, Iris needs Kidney treatment

Our cat,  iris has not been well . Else took her to the pet hospital ,  Iris had to have intravenous treatment for Kidney failure . As we could not get insurance for her, because she had treatment before. We have to pay 10.000 Norwegian kroner's so far , plus the cost of the medicine which will be 5000 nok  . Any amount will help , Thank you.
