Keeping track of your pet’s health information can quickly become overwhelming. Vaccination records, medications, weight changes, dietary notes, and basic demographic details often end up scattered across vet paperwork, notes apps, and memory. That’s why we created Critters, a simple and free pet health record spreadsheet designed to help you keep everything organized in one place.

Critters is an easy-to-use Excel spreadsheet that provides a structured starting point for recording the most important details about your pet’s health and well-being. Whether you have a new puppy, a senior cat, or multiple pets at home, having a central record can make vet visits easier and give you better insight into your pet’s overall health.

What You Can Track with Critters

The spreadsheet is designed to help pet owners maintain a comprehensive health record without unnecessary complexity. With Critters, you can track:

  • Pet demographics such as name, breed, birth date, and microchip information
  • Vaccination records and important immunization dates
  • Medications including dosage and schedule
  • Weight tracking to monitor health changes over time
  • Diet information including food types and feeding notes
  • General health notes and observations
  • More...

Keeping these records in one organized place can help you notice trends, stay on top of vaccinations, and quickly provide information to your veterinarian when needed.

Simple, Safe, and Easy to Use

Critters is built in Microsoft Excel and designed to be straightforward and accessible for anyone comfortable with basic spreadsheets.

The file is also completely safe. It contains:

  • No macros
  • No scripts or code
  • No hidden automation

It’s simply a clean spreadsheet that you can download, open, and start using right away.

Why Keeping Pet Health Records Matters

Maintaining a consistent health record can make a big difference in your pet’s long-term care. Organized records can help you:

  • Prepare for veterinary visits
  • Monitor changes in weight or diet
  • Stay on schedule with vaccines
  • Keep medication details easily accessible

For households with multiple pets, having a central system is especially helpful for staying organized and avoiding missed treatments or appointments. We recommend one spreadsheet per pet.
