Blutak or similar will work fine. I have the same speakers and Blutak forms a very strong bond but does not damage the speakers finish. My own woofer is a mini Dax which is too short to bump into almost anything.

I had used Bluetack substitue. Any hardware store has a bluetack like putty.
The ke to use is the really work the product a lot until it has warmed up from movement and is very pliable. The roll it out to a thin sheet. i had carefully applied a thin layer under my B&W 805S to stands.
The product will really hold, yet can be removed pretty easily.
Blutack or another compound may even have a positive effect on sound by damping vibration at the interface with the support.
I don't have a kids/cats problem any more so when a seller included some Herbie's Grungebuster pads with a pair of speakers, I took off the Blutack and tried those. There's no adhesive on them but they really do make a useful sonic difference for not much money.
Maybe this info will be useful to the OP later on.
