I tried searching for the trading of animals and I found out clear rulings about cats and dogs. I want to ask if we can breed and sell hamsters (the pet mouses)?? Please clarify about it.
To obtain an answer to your Question, I phoned the office of Sayyid Sistani and they said that it is permissible to sell hamsters. You can further refer to mas'alah #2011 in his Tawzihul Masail.
