Take a seat with your cat and have the nail clippers within reach. You can get them comfortable, ideally sitting on your lap, you can pick up a paw one by one and you may need to hold them quite firmly, so they don’t pull away.
When you pick up a paw this should be enough pressure to be able to see the nails.
Be sure to do this in good lighting as you need to be able to see the quick. The quick of the nail is where you can see pink beneath the white nail in the thickest area closest to the paw.
Take your clippers and cut away the tip of the nail, you can take it a little shorter with a second cut if you need to but don’t make them too short. They still need to use them to grip, and you don’t want to cut the quick which will be painful and cause them to bleed.
Once you finish one nail you can quickly move on to the rest. If you or your moggy isn’t used to clipping nails it may be quite a slow start so you will want to give them a little break between clipping each paw.
