Update (Same Day)
I wrote to International Veterinary Hospital asking if they perform pet cremations. They said they are planning to offer the service in the future. Hopefully, I won't need them anytime soon (Inshallah), but it is good to know that a vet hospital is looking into it (and that you can get a quick, respectful response).
I talked to Bu Merdas last night. I was trying not to cry because every time I think of the inevitable, it makes me all sad. He was incredibly supportive and said he would help me when the time comes. He is usually the kind of guy who makes jokes when things get serious, but he was so sympathetic and understanding. He has had the misfortune of having to bury many family members and assist in the burial/funerals of extended family members. I guess this has made him compassionate. I feel a tremendous amount of relief just knowing that I can count on him.
