Ruminants being cud chewing animals digest their food in a fairly complex manner. One important role of the digestion is fermentation of the food in the largest stomach, the rumen. While this fermentation takes place, gas bubbles occur and typically the goat will belch quite often releasing this gas.. which is perfectly normal (and at times can smell really good but this is my opinion *S*)..
Cancerous basal cell tumors are the most common skin cancer in cats. Middle-aged cats are most susceptible to these tumors along with Persians and other long-haired breeds. Many breeds of dogs are predisposed to basal cell tumors, including Wirehaired Pointing Griffons and Kerry Blue and Wheaten Terriers.
Lymphoma, also known as lymphosarcoma, is one of the most common cancers in cats. It accounts for 90% of all blood cancers in cats, and for about a third of all tumors overall in cats. Lymphoma affects the lymphocytes, a type of white blood cell that plays a critical role in the immune system.
