If your furry friend has lost her appetite and appears to be breathing heavy, she could be very ill and needs veterinary attention right away. These symptoms can indicate a variety of very serious medical conditions, many of which can be fatal if not treated quickly.
There are many potential causes which can be attributed to a cat not eating. For example, most diseases, including infectious, autoimmune, respiratory,gastrointestinal, bone, endocrine and neurological diseases, will cause an animal to avoid eating. Pain and internal obstructions, amongst other factors, can cause the affected cat to lose its appetite entirely. Anorexia can also be due to a psychological problem, such as overwhelming stress, major changes in routine, and environmental or dietary changes.
Did you notice your cat’s loss of appetite shortly after you took it to the vet for routine vaccinations? If so, the reason your cat won’t eat may be an adverse reaction to the shots. Although vaccines have been lifesavers for millions of animals, they do cause side effects in some. Loss of appetite is among the more common of these side effects, which are usually temporary and mild.
