Best Rat Colony Management Software in 2026
Summary
Rats are the second most common laboratory animal after mice, and rat colonies come with their own set of management challenges, larger cages, longer study durations, more complex dosing and surgical protocols. The software that tracks a rat colony needs to handle these differences natively. Colony.care supports rat-specific workflows including litter tracking with smaller typical litter sizes, longer gestation periods, and the heavier record-keeping requirements that come with regulated toxicology and safety pharmacology studies where rats are the primary model.
Key Features for Rat Colony Management
Rat-Specific Breeding
Rat litters average 6-12 pups with a ~21-day gestation. Colony.care automatically calculates expected litter dates, tracks actual vs expected litter sizes, and schedules weaning at the correct age. The breeding calendar adapts to rat reproductive biology, not a generic mammal template.
Body Weight & Dosing
Rat studies often involve weight-based dosing. Colony.care tracks body weight over time with structured observation records. Dosing calculations that reference the most recent weight are straightforward because the data is in one place, timestamped and attributable.
GLP Toxicology Workflows
Rats are the backbone of toxicology. Colony.care's indefinite audit trail logs every change, animal identity, cage moves, observations, dosing, with before/after values and user attribution. IACUC protocol linking, study-to-animal traceability, and one-click data exports support GLP-compatible operations.
Top Options Compared
- Colony.care, labs that want a modern, browser-native platform with rat-specific breeding, GLP-ready audit trail, QR cage cards and transparent CAD pricing. Free tier for up to 100 animals.
- SoftMouse.NET, facilities that have used it for years and whose colonies are mice and rats only.
- PyRAT, transgenic facilities that want wellplate management and Transnetyx result import next to their colony records.
- Excel, very small colonies under 20 animals with a single user and no compliance requirements.
FAQ
How is rat colony management different from mouse?
Rats have longer gestation (~21 days vs ~19 for mice), smaller typical litter sizes, longer study durations, and are more commonly used in regulated toxicology and safety pharmacology. The software needs to handle weight-based dosing, surgical records, and GLP documentation differently than for mouse colonies.
Does Colony.care track both rats and mice in the same account?
Yes. Colony.care supports 25 species in a single account. You can manage mouse and rat colonies side by side, each with the correct reproduction model, with role-based access so staff see the species relevant to their work.
Can I import my existing rat colony spreadsheet?
Yes, as CSV. Save your spreadsheet as a CSV file, upload it, map columns to Colony.care fields, preview the import in a dry run, and commit when it looks correct. The import runs as a job with a summary of what was created, updated or skipped.
