Ok so I am new to this site and am looking for some info. I have a 4 month old bengal who was spayed at 3 months (which is when she started spraying ) that is spraying. I have tried everything and have ran uti tests and everything is good. As a last resort the vet said to try Prozac which i couldn't believe but was desperate. Anyone who has dealt with a cat spraying knows my frustration. It is day 3 now and she is doing great, same playful kitten but I found more spray last night. I know its early but was wondering how long it takes for it to start working and if it wasn't successful for some cats. My vet seems very positive that this should work and quick. I am just feeling so hopeless. Please any input would be great! Thank you!
