Vet/Service for In Home Euthanasia?

Posting for a friend... As I wasn't aware of a local vet or service like this, so thought you kind people of reddit may be able to help?

My beloved 18 yo cat was just diagnosed with cancer and some other issues. He’s been my buddy for 16+ years and I’m absolutely heartbroken. He has a large tumor in his abdomen. The vet said he has a few weeks maybe a few months left with us. He’s always hated his cat carrier and man does he put up a fight. He’s the sweetest cat I’ve ever met but once he realizes I’m taking him somewhere he freaks out. I’d hate to put him through that while he’s in pain. If anyone knows of a vet clinic or service that does in home euthanasia when the time comes I’d really appreciate it.
