can the negation also be that some dogs are friendly?

how is "some cats like to drink milk" okay for "one cat likes to drink milk"?? the statement defines and establishes a plural "some cats" like to drink milk...... so does that not mean at least more than one has to like drinking milk?

For the first question couldnt it also mean that Nitten is not a newly arrived cat at Anjellicle Cats Rescue?? I feel like two valid conclusions are there are no cats who were waiting longer than four weeks OR she is a newly arrived cat but at a different shelter.

So Im dying to know, did you make it into UVA law?
