Well, I've been working at home for 14 years and I've yet to find myself looking at pictures of kittens.

I haven't had the issues where someone thinks I'm not going much, neither with remote consultnig nor working for others. I think I'm productive and I show that I get work done, so no one questions my work ethic. Ironically, I find that when I'm in the office, I get much less done during the day. All the distractions you speak of become problematic.

I do find that working at home can be hard. I  usually get up early, and sometimes spend too long at my desk. I eat meals at my desk, talk on calls while doing laundry, have multiple machines around the house and can constantly keep an eye on work. With no commute, there are plenty of days I spend more time working than I did in some offices.

It is lonely, and it can be  a struggle to focus. The same thing happens in the office, it's just different. Over the years I've coped by scheduling lunch with friends or getting outside during the day and breaking things up. A little time spent on another task can help get me in the mindset to get back on the computer.
