No, even wild mice or rats are cancer magnets. If you have a pet rat, it will likely die of cancer.
This is a huge problem for medical research. Imagine that you conduct a safety test of your compound on mice, and 25% of the test group die of cancer within 1 year. That's bad, right? Well, the control group also has 20% cancer rate.
