Okoshi and Usui (1967) reported that around 95% of eggs contained infective-stage larvae after four days of culture at 25C. Infection symptoms are similar to infection by other Toxacara species (T. canis, T. cati). Generally T. cati is more commonly encountered than T. leonina, and both are more common in kittens and young cats than adults. Pfeiffer H. 1983.

Sometimes the worms themselves are vomited up, which can be alarming as they can be quite large with females reaching lengths of up to seven inches. When mothers were infected with 1,000 larvae, the largest number of larvae were recovered from the pups if the mother was infected at parturition. In 1809, Rudolphi had described the ascaridoid of the lion as, and presented a description of a worm with narrow cervical alae. While T. leonina can occur in either dogs or cats, it is far more frequent in cats. Disseminated granulomatous disease in a cat caused by larvae of, Rapic D, Dzakula N, Stojcevic D. 1983.

The genus name "Toxascaris" was created by Leiper (1907) to contain the arrow-headed ascaridoids with smooth eggs, and Ascaris leonina von Linstow, 1902 was designated at the type species. In 1996, 82% of farm cats in Oxfordshire, UK, were reported to be shedding eggs of this parasite (Yamaguchi et al., 1996); Nichol et al., 1981 found only 1.1% of 92 feral cats in London to bein infected with Toxascaris leonina. Both T. canis and T. cati can cause serious disease in puppies and kittens, whereas Ta. The lifecycle of this nematode is similar to that of T. canis except that the dog or cat can only become infected by eating the infective egg or the paratenic host i.e. 1902.

Sprent (1959) and Okosh and Usui (1968) have examined the development of Toxascaris leonina in cats infected by the feeding of embryonated eggs. In mice, they found that the larvae were mainly in the intestine up to seven days after infection, and that the number then decrease gradually and that the larvae disappeared from this organ by the 15th day after infection.

Thus, these authors showed that the infection could be perpetuated in mice by the repeated passage of the larvae. The genus name “Toxascaris” was created by Leiper (1907) to contain the arrow-headed ascaridoids with smooth eggs, and Ascaris leonina von Linstow, 1902 was designated at the type species. "Occasionally, cats can get infected with Toxascaris leonina from a dog."

When larvae from mice were harvested from the carcass 20 to 60 days after infection and orally inoculated into additional mice, larva were again recovered from the carcasses of these mice. The ability of the egg to embryonate at a wide range of temperatures and to become infective as rapidly as four days after being passed in the feces would suggest that infective eggs can rapidly build up in the environment. The roundworm species Toxocara cati and Toxascaris leonina infect cats, while dogs are infected by Toxocara canis. Also, fatal infections may occasionally be seen in young pups.
