I honestly think there's a huge market for a consumer grade "pet" robot. Would love to have one of these running around, then I can just turn it off when I leave

Those are consumer-grade robots, with much better software. (They probably upgraded the motor controllers, too. But those are only crappy because hobby servo technology is stuck in the 1970s.)
Those little OP3 robots are using 250$ each dynamixel digital networked servos.

Yes, those things cost too much due to low demand.
Maybe it's their size or "drunk" motion, but these remind me of toddlers. I would totally get one to just walk around the house doing nothing.
This is already happening, though I’m not aware of any bipedal pet robots.
Any recommendations?
The ones they used are Robotis OP3, a snip at $14,199 each (https://news.ycombinator.com/item?id=35812475)
The Unitree Go1 seems the most promising among the affordable ones.

Would you know whether it’s feasible for hobbyists to make one of these at home by assembling components
Kind of, see: https://odri.discourse.group/

It is indeed pricey though, IIRC the cost of a Boston Dynamics Spot-like robot came down to around $6-7k. There is still room to drive the price down though.

If you're interested in making one by yourself, you should check out Josh Piper[1]

Probably, but not at the price point of $2700.

It would probably be $25k-$50k and 1-3 years of development time depending on your skill set.

I'd recommend XGO-mini2. It just finished it's Kickstarter funding for the version 2, which runs on raspberry pi. (disclaimer, I did contribute to their Kickstarter) and optionally also comes with an arm.
Bunch of servos in human shapes is not too expensive, available from about $1000-1500.
