Do I need a separate clipper for cats versus dogs?

For cats, reviewers strongly prefer small, sharp scissor-style clippers (Japanese-made HIBINO and Necoichi models are recurring favorites in r/CatAdvice) because bulky guillotine clippers can crack thin claws. Larger spring-loaded clippers are better matched to thick dog nails. A few owners use one mid-size clipper for both, but the consensus favors matching blade size to nail thickness.
