Yew berries

Many thanks to those who responded. It looks as though there are many things poisonous to cats so we must be suspicious of all garden and wild plants. The red part of the yew berry is not poisonous to anything but the black seed in the middle is highly toxic to many mammals.

My original query was whether a cat would be poisoned by a mouse that had eaten yew berries. No-one seems to know the answer but it would be difficult to control when the pet is hunter and bringing mice all the time. If the pet goes off colour.........suspect poisoning just in case the vet does not!!
