Not who you were responding to, but in your original statement you wrote "I do not think it’s healthy for adults to do this [sic] I think pets are wonderful for children"

By explicitly calling out that "[they] are wonderful for children" you are implicitly calling into question their value for adults. Whether that was your intention or not, it's certainly how I read your statement.

> I do not think it’s healthy for adults to do this because it infantilizes the adult. ... I think pets are wonderful for children because it helps them to develop a connection with living beings that aren’t humans

This quote heavily implies pets are bad for adults. Maybe it wasn't your intent.
