Complete Physical Maturity: Mice are not done growing until they are between 3 and 5 months of age, depending on the line. Mice should NEVER be bred until they are at least 12 weeks age. If you don't know the line really well, wait until at least 12 weeks, if not longer.wild mice live longer.. around 5 years in captivity, though only around 6 months in the wild due to predators and environmental factors). Maturity: 4 - 8 weeks of age, varying from line to line and mouse to mouse.
A big growth spurt tends to happen in kittens between 2 and 6 months. At around 6 months of age, kittens may start looking adult-sized, although it always depends on the individual animal.It is important during this time frame to feed the little one frequent protein-packed meals, ideally about four times a day.hen it comes to walking like an adult cat, this change tends to happen at a very tender age. When the little fluff balls hit about 6 weeks, they are rather suddenly able to run and walk around just like grown-up cats. This time period is also key for kitten coordination development.
