Sorry, your cat insists on it's right to sit on the window sill and look out
the window. He/she is pushing the lamps off the sill because they are in its
way. Cats get bored and need to entertain themselves by looking out the
window for birds, squirrels or other activity. Unless you can find a way to
permanently mount the lamps or physically clamp them to the window, your cat
is just going to push harder to get them out its way.



When I met my hubby, his cat thought that he owned the kitchen counters
and dining room table. No way do I eat or prepare food where the kitty
has trod. He got trained in a hurry. Fortunately, he was a very sweet
kitty and didn't like being scolded. I had never expected to miss a
cat, but Kitty (his name from former owner) was a sweety, very well
behaved. If the cats are left to use one window, they might be trainable
and leave the others alone, although the lights might be a fascinating
toy. A glob of florist clay under each candle might hold them to the
sill - don't know whether the stuff reacts with metal, but some sort of
clay or putty should hold pretty well.
