my boyfriend already owns 2 rats and has mentioned before how hed like more, I have a friend who rescues rats and currently has 2 pregnant females. My friend said if I wanted I could adopt as many as id like. Im going to get 2 for my boyfriend. Should I tell him before hand? it will be at least 6 weeks before they are here and he already has a massive cage and resources because of his other 2 but I don't know if I should give him some warning? or some cute way of telling him before that.
