OP here, Found these as possible solutions. Still looking for this product with an adjustable alarm volume (as they are 130-140dB, ouch).

1) This one has a double-press button OR a pulltab to activate. I like the idea of the double-press, making it harder to activate accidentally. USB re-chargeable -- https://www.amazon.com/dp/B07VRC47SD/?th=1 2) I found other cat shaped ones and cute ones, but I didn't store them because they had less features and looked harder to muffle without killing the cute look.

I think I will end up purchasing the above item, use duct tape and see if I can get it down to 65-80dB instead of the 130-140dB listed. If so, that might be perfect.
