Is a straw a safe toy for a cat to play with? I came home this morning and someone must have dropped a straw cause Izzy was running around like mad playing with it, then i took it and started playing with her, she loves it! My only concern is she was chomping at the end of it and i had to take it away cause little tiny pieces were breaking off and i was worried she would swallow them. So maybe she can only play with a straw when supervised?
