Yes, rabbits can eat grapes. Adult rabbits can safely eat one or two grapes at a time. Grapes are high in calories and high in sugar so they need to be given in moderation to prevent health issues. If they’re given properly, they make a great treat in addition to your rabbit’s healthy, balanced diet.
Rabbits can eat red and green grapes (and any other color grapes), and they can have both seeded and seedless.
Yes, your rabbit can eat black olives. It’s important that they only have small amounts due to olives having a high sodium level, though. Make sure your rabbit has 100 grams or less of black olives or look for a healthier alternative.
If your rabbit is having black olives for the first time, introduce them slowly. Start with a small piece of olive and monitor for any negative reaction. Watch out for choking and how their gut is responding to the black olive.
Also ensure any pips are properly removed (or get pipless olives). This will greatly decrease the risk of choking.
Yes, your rabbit can eat apples. It will make a delicious and healthy treat for your rabbit. Two slices of apple make a good serving size and should be given around once a week. It’s important to wash the apple and remove the seeds, core, and stem before giving to them though.
No, your rabbit shouldn’t eat canned carrots. This is because the carrots will have been processed with additives to prepare them to be canned. This makes them even unhealthier for your rabbit.
Fresh carrots should only be given to your rabbit on occasion as a treat. The carrot top (green part) is good for your rabbit but the orange part is high in sugars and has too much vitamin A – which makes it an unsuitable snack.
As a result, fresh carrots should only be given to your rabbit in moderation and as a treat in order to prevent health issues from over-eating it. When the carrots come from a can, they are even worse nutritionally for your rabbit and should be avoided.
Yes, rabbits can eat watercress (and other leafy green vegetables) as part of their diet. Alongside hay, water, and a small number of pellets, rabbits are supposed to have a variety of green vegetables as part of their balanced diet.
You can give your rabbit about one cup or a handful of greens for every two pounds that they weigh. Fresh greens are usually given twice per day.
Useful Tip: Before serving watercress to your rabbit, wash it and remove roots and any brown leaves.
Yes, rabbits can undoubtedly enjoy a celery snack! The low-calorie, ultra-crunchy stalks are a fan-favorite for humans and bunnies alike. Make sure you cut the celery into one-inch pieces before serving it to your rabbit. They can eat between half to one full stick as a treat, no more than a couple of times per week.
Yes, rabbits can eat raw carrots. A quarter of a medium-sized carrot is a good amount for a treat. Contrary to a lot of depictions in the media, rabbits should only eat carrots once or twice a week – not any more often.
Rabbits can eat both carrot tops and raw carrots. The green leafy top part (and the stem, leaves, and stalks) are packed full of nutrients and fiber so your rabbit can eat a lot of these. The orange main part of the carrot is high in sugar so you need to limit the amount they eat.
