Can guinea pigs be given crape myrtle branches?

[Lily & the Boars]

I've read it's non-toxic to cats, dogs, and horses, but I haven't found any information for guinea pigs.

I’d err on the side of caution and say no. It looks like a flowering tree...

 

[Lily & the Boars]

does the presence of flowers make a difference?

Partly yes, because I don’t know enough to tell if it’s poisonous to them. I wouldn’t. Hopefully someone else knows and will be able to answer.
@Merab's Slave @VickiA @PigglePuggle @Swissgreys @furryfriends (TEAS) do any of you know about this tree?
