===Withdrawing Treatment===

Environmental modifications that are made outside should be permanently maintained, but glass-etch on windows, food bowls that have been used as spraying deterrents and other minor environmental modifications should be gradually removed after 6-8 weeks without spraying. Psychoactive drug or F3 diffuser therapy should be gradually withdrawn after 6-8 weeks without spraying or after the temporary environmental modifications have been removed. Drugs are withdrawn over a 4-8 week period depending on the duration of therapy. At least two dose decrements are required, first halving the daily dose and then doubling the dose interval. Feliway diffusers are allowed to run out completely, one at a time, after drugs and temporary environmental modifications have been removed. If inter-cat hostility exists in the household then F3 diffusers should be continued until the cats have fully re-established their previous allogrooming and allorubbing [[Feline Communication Behaviour#Affiliative Behaviour|affiliative behaviour]].

Environmental modifications that are made outside should be permanently maintained, but coatings on windows, food bowls that have been used as spraying deterrents and other minor environmental modifications should be gradually removed after a period of 6-8 weeks without spraying. Psychoactive drugs or F3 diffuser therapy should be gradually withdrawn after 6-8 weeks without spraying or after the temporary environmental modifications have been removed. Although not mentioned in the data sheets for psychoactive medications, these drugs should be withdrawn gradually in order to avoid withdrawal effects. In humans, sudden withdrawal of short half-life serotonergic drugs can produce "discontinuation syndrome". Typically the withdrawal period is 1 week per month of treatment, with the dose being reduced in three separate steps (75%, 50% and finally 25% of the original dose). Feliway diffusers can be allowed to run out completely, one at a time, after drugs and temporary environmental modifications have been removed. If inter-cat hostility exists in the household then Feliway diffusers should be continued until the cats have fully re-established their previous allogrooming and allorubbing [[Feline Communication Behaviour#Affiliative Behaviour|affiliative behaviour]].
