Here are the transition words Lisa used in her introduction paragraph, highlighted for ease of identification:
Adopting a shelter pet is a rewarding decision that positively impacts both the animal and the adopter. Firstly, choosing to adopt from a shelter helps reduce the number of homeless animals, addressing the overpopulation crisis in many communities. Additionally, shelter pets often come vaccinated and spayed or neutered, which can save new pet owners significant costs and ensure the animals are healthy. Moreover, adopting a pet from a shelter provides a loving home to an animal in need, creating a deep sense of companionship and gratitude. The benefits of adopting a shelter pet extend beyond the individual, creating a ripple effect of compassion and responsible pet ownership within the community.
