The spokesperson for Scottish Society for the Prevention of Cruelty to Animals (SSPCA) said they were worried about the way the hamsters were killed.

Even though they had done nothing illegal, the shop said that they were "concerned that we may have offended some people."
A spokesperson told Newsround she believed the shop had stopped selling the coats, but would not say why.
