Hi, Is it okay to leave him sit at an open window at night? It gets cold but he loves looking out onto the yard. I'm worried about his getting a respiratory infection. Any suggestions? Thanks.
I'm not sure I would - for the reason you state but also for the possibility that he'll bust through the screen. There may be cats and other critters wandering nearby at night that he might want to chase off or investigate. You might not even know he's gone until morning - and he may be lost by then.
