Tool FAQ
Scope and limits.
Can this calculator confirm pregnancy?
No. It estimates a timeline from a known or likely mating date. Pregnancy confirmation and litter health need veterinary guidance.
What due window does it use?
It uses a broad 60 to 67 day window and highlights the common 63 to 65 day average range.
Editorial boundary
Use the result as a care note, not a diagnosis.
Cat & Meow tools use deterministic rules and plain-language limits. Health-adjacent tools are for organizing observations before veterinary advice, not replacing it.
