If you run a home-based business, you may be surprised to learn that your cat could qualify as a tax-deductible business expense if they help with pest control! While the IRS doesn’t allow deductions for personal pets, there are legitimate ways to write off expenses related to a cat that serves a business purpose.

Below, we’ll explain how you can legally deduct your feline friend as a pest control expense for your home business.

Can You Really Deduct Your Cat on Your Taxes?

The IRS allows business owners to deduct ordinary and necessary expenses for their trade. If your cat helps control pests (such as mice, rats, or insects) in your home office or business, you may be able to claim a portion of their care as a business expense.

However, the key is proving that your cat has a clear business purpose beyond being a beloved pet.

How to Qualify Your Cat as a Pest Control Expense

#1 – Your Cat Must Serve a Business Function

For your cat to be deductible, they must serve a legitimate role in your business. Examples include:

  • Rodent control – If your home office or business space has had pest issues, your cat’s hunting instincts could qualify it as a form of pest management.
  • Warehouse or storage protection – A cat that deters mice from damaging goods could be considered a business expense if you store inventory at home.
  • Farm or homestead businesses – Cats are often used for rodent control in agricultural settings, making them a deductible expense for farmers.

#2 – Document the Business Use

The IRS requires proof that your cat is more than just a pet. Keep records such as:

  • Receipts for pest control services before getting the cat (to show an existing need).
  • Photos or videos of your cat catching pests in your business space.
  • A written log noting pest sightings and your cat’s role in controlling them.

#3 – Calculate the Deductible Expenses

 You can’t deduct 100% of your cat’s expenses unless they solely serve the needs of your business. If your cat spends time in your home office or business area, though, you may deduct a percentage of their costs, including: 

  • Food & treats
  • Veterinary bills
  • Litter & grooming supplies
  • Training (if applicable)

Example Calculation:
If your home office takes up 10% of your home’s square footage, you could deduct 10% of your cat’s expenses as a business cost.

Potential Pitfalls to Avoid

  • Don’t claim your pet if they don’t serve a business purpose. The IRS may disallow the deduction if your cat is purely a companion.
  • Avoid overstating the deduction. Only claim the portion related to business use.
  • Keep thorough records. Receipts, logs, and documentation are crucial in case of an audit.

Other Possible Pet-Related Tax Deductions

If your cat doesn’t qualify for pest control deductions, consider these other potential tax breaks:

  • Service animals (if prescribed for a medical condition).
  • Foster pets (if you volunteer for a qualified 501(c)(3) rescue organization).
  • Pure-bred or show cats (if part of a legitimate business).

Final Thoughts

While deducting your cat as a pest control expense is possible, it requires careful documentation and a legitimate business need. If your feline friend helps keep your workspace rodent-free, a tax professional can help you legally maximize your deductions.
