Donate towards Oliver's surgery

Hey guys we normally dont do this. But back in March, my sister's cat Oliver became sick out of nowhere. We took him to the vet and was told he has Gastrointestinal issues and started getting severely constipiated/blocked. Of course thinking this could be a temporary problem, we were wrong. He has since been to multiple vets and has been put on a couple different medicines. Things were looking better over the past couple of months, but now they think it could be another underlying issue. He needs more blood work done, consultations and even surgery. He has lost alot of weight as well. Vets can be very expensive, so we are looking to see if anyone would like to donate and help us get our Oliver some help. He is only 6 years old. Times are hard for everybody, we understand. Anything will help, even a share. We appreciate you guys so much. And Thank you!
