How can I prevent my 5 kg cat from licking my psoriasis ointment off my arm while we sleep?

Short answer

Prevention is crucial because ingestion can be toxic. Store all tubes and jars in a latched cabinet your cat cannot open, and apply ointments well before bedtime so it absorbs. Wear a long-sleeved shirt or use a breathable bandage to cover treated skin, and consistently reinforce the 'leave it' command with treats to discourage licking. If your cat does lick any cream, wash the area with mild soap and call your vet or the ASPCA poison line at 888-426-4435 with the product name.

Why is this dangerous?

Pets have thin skin and a large surface-to-weight ratio, so a topical steroid, hormone gel, pain cream or psoriasis ointment applied for a human can be absorbed in meaningful amounts.

The bigger problem is grooming: a pet that licks the cream off its own or its owner’s skin swallows the whole dose. Vitamin D analogue ointments and calcipotriene are especially dangerous.

Why speed matters

Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.

Signs to watch for

  • Vomiting, drooling, not eating
  • Increased thirst and urination (steroid effect)
  • Weakness, wobbliness, tremors
  • Skin redness or irritation where the cream was applied
  • Kidney-signs and high calcium days later (vitamin D creams)

What to do right now

  1. Wash the cream off with mild soap and warm water before the pet can lick it.
  2. Call your vet or a poison line and name the product — the active ingredient decides the risk.
  3. Never apply human creams to a pet without veterinary advice.
  4. Cover treated skin with clothing or a bandage if a pet shares your bed.
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
