This is a really handy reference book for cat owners. The advice is given responsibly, without being alarmist. A lot of references will tell you to rush straight to the vet at the first sign of any symptom, whereas this book explains why it may or may not be necessary, and gives you a better understanding of the broad range of circumstances that might lead to the symptoms. It also has practical ways things you can do at home to narrow the list of potential causes, and safely alleviate symptoms. The book is also suitable for international use, without a lot of references to US-specific products or treatments.
