One minor thing, and I am sure you know -

Give the Feliway or whatever you are using a good shake - 'shake well before spraying'. Maybe the ingredients aren't getting mixed as they should.

Oscar's original dose was 2 - 3 shots a day; cats need 4 hrs exposure at a given time. So don't be afraid to up the number of doses.

Glad he is healing so well.

Now just CHILL OUT, Taz!
