As mentioned in an earlier comment, despite installing the mod, I can still interact with my pet just fine, both out in the open and when it's in front of a container I'm trying to access. I'm playing on a vanilla server as a Human with a few clientside mods installed.

Here is my starbound.log after briefly logging in and interacting with my pet. (server IP redacted)
https://0x0.st/HOTV.txt

This line may be of note, though I believe it's from trying and failing to bind interact to one of my mouse buttons in addition to some keyboard keys. Unsure if that would cause issues.
[21:52:21.997] [Warn] Could not load keybinding for PlayerInteract. (StarException) Improper bindings type 'mouse'

Here is my starbound.config (server IP redacted again)
https://0x0.st/HOTW.json

The interact binding section looks like this:
```
"PlayerInteract" : [{
"mods" : [],
"type" : "key",
"value" : "W"
}, {
"mods" : [],
"type" : "key",
"value" : "A"
}, {
"mods" : [],
"type" : "mouse",
"value" : "FifthButton"
}],
```

I am using the Workman layout so my keys are not in the usual qwerty spots, so my bindings may seem odd, with interact on W and A keys. I wanted it also on the "back" button of my mouse, but couldn't seem to get that working with either "FourthButton" or "FifthButton" values. I suspect they removed support for binding mouse buttons.

Let me know if you need more info or testing from me.

The mod just turn "monster.setInteractive(true)" into "monster.setInteractive(false)" (in groundPet.ua file), so it dont change key in any way.

Even if you changed your key it should work so i dont see why it won't work here.

Did you check if log say the same thing when you havent that mod instaled ?

I've just tried unsubscribing, going in game, and doing the same stuff. I see the same error about the mouse bind in the log still, yes. So that should be unrelated to the issue.

edit: I also took the mouse bind parts that don't work out of my config and reinstalled the mod and it still doesn't work, FYI.

So if you have the issue without the mod , its a proof it's not caused by it.

I've check your workman layout thing and seeing that , you should try R key maybe , i use E for interraction (azerty keyboard) , and R is at the same place.

But yeah since the issue don't come from my mod, and i'm not familiar with a heavily keybinding swaped like that, you may need to ask to someone who had the same issue or a general starbound discord since your issue is maybe vanilla.

I use an esdf-style layout instead of wasd-style also (lets me keep my fingers on the homerow instead of one off), so r is my up key. I think I did try that, but since it's not my interact key it's of course not going to interact. A and W both work fine for opening storage in general, this mod is just not disabling the cat interaction like I would expect.
The issue we're discussing is that I can interact with my pet always even with your mod, so it's of course related to the mod. The non-serious error about the mouse binding in the log was not related to your mod, yes, it's also not causing any problems, and I've since taken it out anyway just to eliminate one possible cause (though it seems to have not been the cause), so no need to worry about the mouse type error.
Once again the issue is that your mod is literally not working at all (for me) from what I can tell, at least when only used on the client and playing on a vanilla server. I know I mentioned a lot of barely-related stuff so maybe I confused you.

"at least when only used on the client and playing on a vanilla server"

I never said it was client-side.

Oh, come on... My very first comment was asking if it was clientside, then you said it should work in multiplayer. If it needs to be on the server that could've been made more clear from the start.

Where did i said it work on MP ?

my posts above aren't modified, you can check again.

LOL. On the workshop's comments, not in this thread. Anyway, I think we're finally on the same page. Thank you for your time.
