Typically, if you can see the rabbit’s nails really easily past their fur, they probably need to be trimmed. Depending on the rabbit, nails need to be trimmed regularly, in intervals of per month or multiple months.

Are the nails black or white? Also some may have both, depending on the nail. If they’re white, take a look and identify where the quick is, which is the bloodline. Where the quick ends to the end of the nail is the appropriate place to cut. If, without getting too close to the quick, you can place nail clippers and cut some nail off, it’s time to do that.

For black nails, you can reference other white nails for comparison. If your rabbit has all black nails, you can use a light and try and find the quick by shining it through. If that doesn’t work, I recommend getting a rabbit vet to do it first, then you take some time to evaluate the length after trim and remember it so the next time, you have a good idea of length.

The quick will adapt with nail length over time, so if they stay long for a while, the quick will grow longer. If you keep the nails relatively short, the quick will stay closer to the paw.

If you Google rabbit nail trimmings, there are great informational visual images and videos to reference.

Once they’re cut, they will not curl down as much, making them less likely to scratch you, fyi.
