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.
1 Multicentric lymphoma - generally involves multiple lymph nodes and possibly multiple organs. This form is more closely associated with feline leukemia and the prognosis for this form is not as good, especially if the cat is feline leukemia positive.  Mesenteric lymphoma - very common in cats over 10 years of age. The intestinal form affects the small intestine but sometimes the stomach, leading to gastric lymphoma. This form is least likely to be associated with feline leukemia.
