Questions about my new guinea pig...?

first off he aint used to u yet give it time chatch him and gentley stroke him and let him get used to u dont freak out if he nibbles on you. second critter igloos work wonderfully they use it to have time to them selves and it is easyer to chatch them cause then all u have to do is wait for them to go inside and then lift up the igloo and chatch him. and yes they will be perfectly fine by them selves at night. (dont give it a bath cuase it will make it sick and die ) personal exsperiance
