Soda, your dream seems to be rich with symbolism and reflects a community or a sense of belonging, as well as your nurturing instincts. The presence of stray cats and your concern for Kirby's well-being suggest that you are someone who cares deeply for others, particularly those who might be vulnerable or in need of help. These cats finding harmony with Kirby could symbolize different aspects of your personality or life that are starting to come together peacefully.
The act of spaying and neutering the cats can symbolize a need for responsibility and taking control of a situation that has the potential to become overwhelming. The fact that you're talking about it, but not necessarily doing it in the dream, may indicate some procrastination or hesitation in making decisions in your waking life.
Mowing the lawn with others is another communal activity in your dream, which could represent teamwork or collaboration in your life. The transition from tending to animals to tending to the lawn could mean you're looking to cultivate not just relationships but also your environment or perhaps your personal growth.
The husky and the person with the child introduce the theme of social boundaries and the awareness of others' space. Your hesitation to pet the dog upon noticing the owner could be a reflection of your respect for boundaries or an indication of social cautiousness.
The pumpkins and the involvement of your grandma bring elements of tradition, family, and generational connection. The idea of a pumpkin exchange and the blue painted pumpkin left for you suggest that you're open to new experiences and exchanges of goodwill within your community.
In all, your dream paints a picture of someone who is deeply connected to their community and family, values harmony among different elements of their life, and is conscious of social dynamics and responsibilities. These themes are common in the lives of young adults navigating the balance between individuality and community, which seems very much in line with your age and experiences.
