Rats are social animals who need to have at least one rat companion.
Cage mates are best introduced between 5 and 9 weeks of age, before they reach maturity.
Rats like a cage with plenty of hidey-holes and levels that they can climb up onto.
Don't feed your rats treats through their cage bars or they'll get used to biting anything put through the bars like fingers.
Never pick a rat up by his/her tail.� Use both hands to scoop the rat up.
Give them a rich environment by putting tubes, paper towels, toys, small branches, rope ladders and anything else that looks fun to climb in, on or over.
Feed your rats a good diet (see the food section) and keep unhealthy treats to a minimum. Hide food in different areas around the cage so the rats have to hunt for it.
Gently handle your rats on a daily basis and make it a pleasant experience for them.
Rats are more active during the evenings and early mornings ? they will particularly enjoy your attention then.
Be mindful of how sensitive your rats' sense of smell is. Don't over clean your rats' cage with detergents which have an over-powerful smell.
