My friends cat died yeasterday due to congestive heart failure. She is having a very hard time here at work today. I wish there was something I could do to make her feel better. Shakespeare was 11 years old and was an only cat. My friend first thought the reason of the heart condition was because of her move to her new house on friday. The vet told her that congestive heart failure was not caused by stress. This made her feel a little better. Is there anything I can do or say to make her feel a little better? She already visited the rainbow bridge site. Any advise on what I could do for her?
