There are a couple of episodes where #Garfield appears on #USAcres / #OrsonsFarm:
- Mystery Guest: https://youtu.be/UYnAZuKkJ8c
- Fast Food: https://youtu.be/1KBP3SRY4H0
- Quack to the Future (though mostly as a cameo): https://youtu.be/u5DxML4DPPQ
- the thing in the box (though only #Nermal meets Orson and his friends there; Garfield is merely seen mailing the kitten): https://youtu.be/1HTAILvfjw8

But yeah, I don't get the impression they are friends; at least not close ones.
