There Is No Felliway Outside

AYLA:  I don't know what it is about outside, but Iza treats me like an introoder kitty when we are on the deck.  Its hard being the smallest cat in the house, but it is harder outside.

Somedimes I stand my ground, but it doesn't usually help much.  I weigh 7 pounds, Iza weighs 12.  

I have faster whappy paws, an I can bunny kick pawsomely, but it has no effect on her.  I usually just go sit on the top of the fence cause Iza can't bother me there.

Mebbe I should stay stay inside near the Felliway dispenser...  But I need some advice.  Marley isn't protecting me the way he used to.  Should TBT double the Felliway?  Or do something else?
