for plants....or you buy herb for cats (flowers shops) or you put them all up... i have that problem with my demons so i have done both....some plants are toxic for plants ...so be careful....
for the hair ...you could comb him....but he's a long hair cat ... like Siberians,Persans etc....
to be sure he will do what he has to do 'in privacy' (

) nowhere else but where he has to ,put few drops of bleach in litter ....
out of that ,i don't think you could have any problem....he will probably try to hunt flies & butterflies....
make sure he has fresh food & fresh water in bolws (change water everyday)...cats hate dirty stuffs& old food....
good luck & have great fun .....
