Are you sure your bunny needs to gain weight? Most house rabbits tend to be bigger than they need to be but that’s just because we spoil them! And overweight bunnies tend to have health issues. Is this weight-gain vet recommended? If so, here are some tips…
Timothy hay and timothy pellets are what is usually recommended to feed an adult rabbit. Baby rabbits (under a year) should eat alfalfa hay and alfalfa pellets because it will help them to grow. Rabbit meat farmers also feed alfalfa to “fatten up” their stock
. So try switching from Timothy to alfalfa hay and pellets – this should help put on weight.
I wouldn’t necessarily give more treats – it will put weight on them but all the extra sugar can also cause tummy upset, so I don’t suggest that route.
You can also try supplimenting with Critical Care. Critical Care is a food suppliment fed to bunnies who have stopped eating for whatever reason (usually illness). It’s packed with all the nutrients a bunny needs to live and you can get it from any vet that treats rabbits. It comes in powder form – you add water and dispense with a feeding syringe (from the vet also) but some bunnies like the taste and will eat it right out of a bowl.
I volunteer for a rabbit rescue and sometimes we get bunnies that are very underweight. Usually a few weeks on alfalfa and the weight slowly goes up. Also, 1/8 of a cup of pellets per 5lb of bunn is the norm – but in this case, go ahead and give 1/4 to 1/2 per day. And don’t forget plenty of fresh greens every day!
Keep a close eye on the teeth – teeth issues can result in a bunn not wanting to eat, so get them well checked. The vet should use a scope to see them all properly – spurs can be painful so keeping the teeth nice and straight and flat will help your bunny to eat more.
And monitor the weight gain – once you get to the proper weight, cut back on the pellets and slowly switch back to timothy hay and pellets (by mixing them at first, then slowly stop serving the alfalfa altogether).
Good luck!
