Cat Death

[Suninfrance]

My friends returned home yesterday lunchtime to find one of their cats dead.  Her bottom half (chin, legs, stomach and bottom of her tail) were covered in a yellow, oil based liquid.  Is there some kind of weedkiller or pesticide that fits this description.

The cat has been taken to the vets who will hopefully do a post mortem to find out the cause.  We wondered whether she has walked through an area that had been sprayed and then tried to wash herself, ingesting the poison.

They showed me a photograph of the poor cat and it was so distressing, so if anyone has any ideas what this substance might be then the source can hopefully be found and the person using it, asked not to use it again.

Any help gratefully received.
