To finish our investigation, we've asked the other Thundercats for their opinion of Snarf.
The results we got were a little overwhelming, so we asked each Thundercat to summarize, in one sentence, what they wanted to say about Snarf.
Here is what they said.

I hate it when he leaves wet paw prints all over the back of the Thundertank.--Panthro

Watch his tail around chemicals, because it can be unpredictable.--Tygra

Someday, I'll get him to ride a spaceboard.--Wiley Kit

Someday, I'll beat him in a game of kick-the-bucket.--Wiley Kat

Depending on what he's making, Snarf can be a pretty good cook.--Pumyra

I wouldn't let him get within ten feet of a hammer.--Bengali

Cute you guys.  Very cute.  But you'll all realize that without me, you would be nothing.  I AM the Thundercat team.  And Lion-O?  We need to have a chat.--Snarf
