For example, benign tumors are mostly well differentiated and malignant tumors are often undifferentiated. However, undifferentiated benign tumors and differentiated malignant tumors can occur. Although benign tumors generally grow slowly, cases of fast growing benign tumors have also been documented.Some malignant tumors are mostly non-metastatic such as in the case of basal cell carcinoma.lso, benign tumors generally have a slower growth rate than malignant tumors and the tumor cells are usually more differentiated (cells have normal features).
How a kitten contracts a worm depends on the type of worm it is. Roundworms and hookworms can be contracted by sharing a litter box with an infected cat. He can also get roundworms from his mother's milk if she was infected. Tapeworms have to be ingested, usually via a flea or rodent that was infected with tapeworms.
Roundworms are most commonly passed from adult mother cats to their kittens through the mammary glands. Kittens are at highest risk for health concerns related to roundworm infection, but adult cats can be infected by ingesting eggs from infected feces or intermediate hosts such as earthworms or rodents. Roundworm infection is called 'ascariasis' and generally does not produce symptoms in adult cats.
