Neem oil is almost non-toxic to mammals and birds. It has a bitter taste; this will deter your pets from licking neem oil off plants. Despite the lack of toxicity to these animals, it can be moderately toxic to fish and other aquatic animals. To prevent contamination, avoid using neem oil near ponds or open water sources.
Neem oil is only toxic when a treated plant is ingested, so bees and other beneficial insects and wildlife are unlikely to be affected by it.
When cats and dogs become sick, neem oil can be a good remedy for their ailments. It can be used as a flea treatment or as a shampoo for skin conditions. It can also be used to repel and kill parasites, although neem oil is not the only insect repellent that can be used.
Neem oil can also be used to treat skin conditions. As it is very potent, it is recommended that it is mixed with carrier oil, such as coconut oil or olive oil. Use 10-12 drops of neem oil in 30ml of your base oil. You can also add a few drops to a good quality animal shampoo, and apply as normal.
Another good alternative to shampoo and oils is the use of a spray solution to treat fleas. Once you apply to your pet, leave it on for 20 minutes, before washing off as normal.
