After a very upsetting experience of My cat pepper being sick we came to realize that it was caused by what we thought were harmless cat toys. It started when we noticed that she had been vomiting. It was yellow and foamy. I called the vet and we took her in to be checked out. after x rays, the vet noticed that there was a consistency in her intestines, but we were unsure of what the obstruction was. After a surgical proceedure it was discovered that Pepper had swallowed the string tail off of one of her toy mice. If we had not caught it right away, the string could have caused lacerations in her intestice which would cause internal bleeding. I had no idea that her toy mouse could have been a potential danger to her. I am wanrning all cat owners to please supervise your pet while playing with any toy with string. I had never known her to swallow any toy before and we are very lucky that she is okay.
