My Rosie was crazy about that glossy finish the photoshops used to put on photographs. And I remember hearing from other cat parents that their cats loved the stuff too. Of course it was toxic to cats, so to keep them safe we had to keep them away from photographs.
As for dishwashing liquid and other things, just because they like the smell or even the taste of something, it doesn't mean it's good for them and that they should be allowed to have it. (Antifreeze containing ethylene glycol might be the most perfect example of this.)
Getting back to soapy dish water.....two of my cats (at different times, years apart) started going into the kitchen sink searching for something, anything, to drink when they were sick with cancer. (Excessive thirst caused by the disease was driving the behavior.) Bernie would even get into the bathroom sink and bathtub looking for water. It was scary and heartbreaking. With both cats, keeping a large bowl of water right next to the kitchen sink proved to be very helpful. They were drinking from that very nicely instead of going into the sink. But poor Bernie, he was in the bathtub again just minutes before it was time for us to leave for that last vet visit.
A couple of months ago, for the first time in her life, my Tabby also started going into the kitchen sink looking for a drink. And I noticed she was drinking more than usual as well. I was horrified, fearing the worst. But a few days later I was able to breathe a huge big sigh of relief when it turned out that a new food (canned!!! not even dry) I had just started buying was the reason she was suddenly so thirsty. I'll never know why that food had that effect on her, but no more of it has solved the problem. Her drinking went right back to normal and she hasn't been near the dishes in the sink since.
So, anyway.....I'd just like to add, you're absolutely right when you say "I really have to be on top of things with her." It seems our babies always find reasons for us to do that, don't they?
