Droopers - a warning about collars on cats. These can trap a cat and cause a lot of suffering. I took in one old girl cat who strayed around here (they all seemed to) and she was really suffering. Not only had the collar at some time been caught up to cause awful damage to her neck, she had grown a bit and the remains of it were embedded in her skin. It took a long time to put all the damage as right as I could. Happily, she did recover and finished her life here in comfort. I haven't used collars on any cats or dogs ever since this. Harnesses are preferable, and then only when necessary, not full time.
