Rat Questions!
How old are rats when they are able to breed? (Mine are less than a year and I want to know when I can breed them)
What are the best ways to encourage breeding?
What is the best way to move a pregnant rat to have her own space, such as a separate tank for her to have a ton of space?
How old are rats when they stop growing? (My males have gotten bigger but my females haven't and I'm a worried rat parent)

Any other rat related info would be great!
Thank you(:

they should be 15 months of age.  Rats tend to grow rapidly, about 1" per month, until about 3 months of age when growth slows. A female rat will stop growing at about 6-7 months of age, and a male at about 8-9 months.

Explanation:

im sorry i cant really figure out how to answer the other questions, i hope this helps!

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

here's your answer.
