Is the hormone injections acting as a form of "anti depressant". Our 11 year old cat was attacked by a dog a year ago and ever since then has to continually mark every curtain, childrens toy, bench etc in the house - worse when he hears dogs barking. I took him to the vet and the vet said he can be given an anti depressant to calm him down and lessen the trauma in his head. We are unable to give him the tablets and it is very expensive in the syringe form so we are at the stage of putting up with it for the love of our cat. If it continues to get worse (surely it cant!! ) he will have to be pts.
