Yes you remembered correctly, usually it's three full days. My friend just sent me this pic, so cute. As Koda is getting older he's becoming much more chill, but he still is moody. And still a dick. Last time they visited, even Lilly preferred staying in the rest of the apartment with Miez rather than with him in the living room where the cat walls are - even though the two of them (L&M) hissed at each other.

Edit: Improved my English.
