There is spraying and there is obsessive spraying! At my wits end I finally decided to try medication. The vet prescribed something called Kalm to try for a few days before starting on the clomicalm. Done that and there was no change in his behaviour. Gave him the first dose of clomi yesterday but only 5mg which is half the amount prescribed. No side effects so far… he is his usual self but perhaps a little calmer and there was less spraying. Dare I hope?
