SSRIs affect the brain chemical called serotonin. Common SSRIs are fluoxetine (Reconcile or Prozac), paroxetine (Paxil) and sertraline (Zoloft).

SSRIs are used to treat a number of anxiety-related behaviour problems. These include the fearful avoidance of the litter box, the fear of other cats in the house, or aggression toward other cats. SSRIs help reduce compulsive behaviours, such as excessive grooming. SSRIs need to be taken everyday to be effective.

Costs and Side Effects

A cat can be on anti-anxiety tablets for the rest of its life. Feline anti-anxiety meds can cost anywhere from $60- $80 a month. Of course, there are some anti-anxiety meds made for humans that cost less and can be given to cats. But these human anti-anxiety meds aren’t always safe for cats. For example, paracetamol could kill a cat.
