Filed Under: Dogs, Cats, Diseases

Fibrosarcomas are malignant tumors of fibroblasts. Fibroblasts are cells within the dermis of the skin that produce the collagen in connective tissue. These tumors are locally invasive, often recur locally, and have a tendency to spread to other parts of the body (metastasize). Metastasis often occurs weeks to months following surgical removal. Fibrosarcomas are hard to control through surgery even when ancillary therapy like chemo or radiation is employed.

Filed Under: Cats, Diseases

Feline Leukemia is a retrovirus. As a member of the retrovirus family, the feline leukemia virus’s genetic material is transmitted as RNA. Once the virus infects the cell, DNA copies of the virus are transcribed and these copies are inserted randomly into the host’s genetic material. Once the DNA is integrated within the genome, any cell division that occurs will cause both of the new cells to contain the virus.
