Hello, welcome to Just Answer. I am sorry to hear about Britney passing away and the grief that you are experiencing. One thing that I find will lessen my pain in losing a pet is to have them cremated and have the ashes returned, as you have also pursued. While it is expensive to do this through your veterinarian's office, I should mention that most vet offices do not do the cremations on site and will contract this service out to a specific company. This company is generally the one that sets the cost for cremation, and the veterinarian passes this along to the client. One option you may want to consider is contacting a local human funeral home to see if they will provide cremation services for your cat at a more affordable cost. Good luck, and again, my condolences.
