Here are some ways YOU can help keep sloths healthy and safe:
– It is best to observe them from a distance and in silence.
– Our pets could attack them. It is important to keep your dog on a leash when you go for a walk, or keep your pets at home in an enclosed and safe area. In addition, taking care of our pets also means spaying and neutering them so that they do not breed without control.
– Sloths love to live in the woods, keeping them as pets is not good for them. Keep in mind that they don’t like selfies either.
– If you find an injured sloth, contact a wildlife hospital so they can help it.
– Deforestation is often caused to make more land for livestock. Eating less meat may help save our forests.
