I accidentally killed a lizard that snuck in to our house while trying to save his life

My wife screamed when she saw it and then proceeded to try to capture it so we can let it out of the house or else our cats will torture it/play with it. Lizard was elusive and it ran away and disappeared. I went in to the kitchen hours after she slept to get some water and saw it laying there. Didn’t know what to do. Cats were already in hunting mode. I shoo’d my cats away. It was 11:30 and I had work tomorrow so since it was hard to catch I just put the biggest bowl we have over it and decided I would take care of it in the morning. Woke up to my wife crying because the lizard suffocated in there and died. I feel terrible 😞
