Make Bromethalin rat poison illegal in the U.K. Because of the dangers to pets

On Friday the 14th of October 2016 I found my cat grubby and walking into things,she was a wild cat and was always outside.we noticed she was walking into things and her eyes looked weird, we realised she was blind. We brought her to the vet and they referred us to the hospital for her they said they would keep her over night, we got a call the next morning.she had been sick green stuff and she was much worse the vet said she was poisoned by a type of rat poison and we had to put her down.
