Don&#x27;t know about cats, but I&#x27;ve had a dog that we fed doggie Prozac in an attempt to help with behavioral issues. Seemed to have a positive effect (unfortunately, not positive enough; had to eventually put him down). We volunteer at an animal shelter, and there are occasionally particularly anxious dogs that get a prescription. Works well for a lot of them, it seems, or at least takes enough of the edge off that they can be worked with and trained.<p>Not sure of the colloquial meaning of &quot;barmy&quot; (and the Mac OS dictionary is no help), but if it&#x27;s a negative term, I&#x27;d argue that observation says it can help in some situations.
