Lemme Smash
Yiff

Several other spots, VR chat is more popular as it is the future if you will but SL still has some spots.

Its also full of children. If you don't already have a big friend group in it, most of the people I run into on there any time other than three am are underage. It's the one reason I refuse to invest in VR chat D:
Sl is better for adult entertainment if you know the right spots. VR chat is good for bursts of experience with friends you already have
(My personal opinion)

Pet Adoption Center is for all sorts and usually has someone around.
The Waste is a furry dive bar that's pretty fun.

Fox on the Run and Boiling Point are both clubs. When the DJs are on there is usually a group and they are very talkative and friendly.

There are two furry clubs I have residency at, meaning I DJ/work there. I’ll be happy to invite you to them and hangout!
