Careful reading and patience. No maths is needed, but you should be comfortable ruling things out one clue at a time.

How it works
Draw a grid with one category across and another down.
Mark ✗ for impossible pairs and ✓ for confirmed ones.
When you place a ✓, put ✗ in the rest of that row and column.
Revisit every clue after each new ✓ — clues combine.
Practice puzzle: Amir, Bea and Cal each have one pet — a cat, a dog or a fish. Clue 1: Bea is allergic to fur. Clue 2: Amir's pet does not bark. Clue 3: Cal walks his pet in the park every day.
Worked example 1
Solve the practice puzzle.
Clue 1: Bea cannot have a cat or dog → Bea has the fish.
Clue 3: pets walked in the park are dogs → Cal has the dog.
That leaves the cat for Amir, which fits clue 2.
Answer: Amir – cat, Bea – fish, Cal – dog
