Urgent Help for Ashleigh's Beloved Cat Olaf

My daughter Ashleigh's cat, Olaf, has recently become ill and has had numerous visits to the animal hospital. They have kept him now on medication and an IV. They informed us today of the need to go in to empty his bladder and that he also has a gall bladder obstruction. He will now have to have it removed. We are praying for the best outcome. As we all know, vet bills add up quickly. To some, he may be a cat, but anyone who knows my daughter Ashleigh knows this is her baby. It is financially stressful, and with her being a student and working as much as possible, it is going to be overwhelming with vet bills. It would be greatly appreciated for any help, no matter what it may be. Prayers for our little guy are always welcome.
