A friend of mine has a cat and one day she woke up found the cat got swollen up in one night - almost changed completely to another cat. But apart from the looking the cat was still eating and drinking as normal. She was rather worried and posted the cat's photo on a local forum to seek advice and help.
At the end of the day she found out the reason - the cat climbed up to her table with tale brushed onto her aromatic burner. There was just several drops of diluted essential oils in it and the cat didn't go for it. But it inevitably ate some while cleaning the tale......So the essential oil sort of poisoned the cat .....
The cat got over it the next day as she didn't have many and the oil was diluted. But that gave her a big heart attack...
As I know aromatic products are quite common and popular here, I think it might worth mentioning to all cat owners....
Just look at the pic to see the effect
