| + | ==Cat== |
| + | *A canine parasite - see under Dog Nematodes for life-cycle etc. |
| + | *Cats are abnormal hosts, and so ''D. immitis'' is not very infective for cats. |
| + | *Nevertheless, feline infection is common (up to 25%) in some heavily endemic areas. |
| + | *But only small numbers of adult worms (1-3) establish. |
| + | *The prepatent period is longer (approximately 8months) than in the dog. |
| + | *Few, if any, microfilariae are produced (<20% of cases positive). |
| + | *The life-span of the worm is shorter (2-3years). |
| + | *However: one dead adult → acute pulmonary crisis (thromboembolism). |

| + | === Feline Heartworm Disease === |
| + | *Lung pathology similar to dog, but little heart pathology. |
| + | *Coughing starts 4-6months post-infection. |
| + | *Antibody-detection ELISA used for diagnosis, but false positives occur (antigen ELISA cannot be used as antigen rarely expressed in cats). |
| + | *There is no licensed adulticidal therapy, and treatment may be fatal for the cat as well as the worm. |
| + | *Ivermectin or selamectin can be used for prevention. |
