What's the highest level you can be on for your pet's job?

i also wish i knew. nowadays, i didnt collect the money from there. maybe i should just go do that >.>

I saw someone post a few days ago that they had got to level 8 with a Library job.

No idea how high you can actually go though. I'm currently level 5, and don't want to push my luck, I'm sick of getting fired xD
