Recovery feeding is a vet-led project
A rabbit that has lost weight through illness is not simply a thin rabbit. The underlying cause — dental pain, gut disease, infection, or another problem found during treatment — shapes what it can eat, how fast weight should return, and which foods are safe to push. So this plan runs under your vet's guidance from the start: confirm the target weight, the rate of gain your vet wants to see, and exactly which foods and any vet-supplied recovery feeds to use, then check in on the schedule agreed rather than freelancing when progress feels slow.
What follows is the general shape of most recovery plans, to help you run yours well and ask good questions at each review.
Hay still comes first, presented to tempt
Even a rabbit that needs more calories needs its gut moving and its teeth wearing, so hay stays unlimited throughout recovery. A convalescent rabbit may eat more if hay is offered in several places — rack, litter tray, a pile beside its resting spot — and if you offer more than one suitable hay so it can choose the strands it prefers that day. Fresh handfuls added little and often smell more appealing than a large stale pile.
If hay intake is poor, tell your vet rather than compensating with large amounts of rich food. Low hay intake after illness often means the original problem, especially dental pain, is not fully resolved, and piling in pellets can slow the gut further and mask the real issue.
Increasing energy carefully and gradually
Where your vet advises more energy, the usual lever is a modest, gradual increase in the measured pellet portion, sometimes with a switch to a pellet type your vet recommends for recovery or for young growing rabbits, introduced over several days. Add calorie-supporting greens and herbs your rabbit already tolerates — coriander, parsley, dandelion, leafy tops — and small amounts of richer vegetables if your vet agrees. Oats and other energy-dense extras are sometimes suggested in recovery, but only in the small quantities and circumstances your vet specifies, because overdoing them risks digestive upset and selective eating.
Any syringe or recovery feeding product should be the one your vet has supplied or named, given at the frequency agreed. If your rabbit begins eating voluntarily, ask before stopping assisted feeding; appetite often returns in waves during recovery.
Monitoring: weights, droppings, and appetite
Weigh weekly at the same time of day on the same scales, ideally kitchen scales with the rabbit in a carrier, and write the number down. Feel is misleading in a fluffy rabbit, and memory flatters progress. Alongside weight, keep a daily note of hay eaten, droppings produced — quantity and size are a practical gut-health gauge — water drunk, and general brightness.
Report back at the agreed points, and sooner if weight falls again, droppings shrink or stop, or appetite fades after improving. Those setbacks are information your vet needs promptly, not failures to hide. A rabbit that stops eating entirely is an emergency for this species, whatever stage of recovery it has reached.
Protecting the gain once it arrives
As your rabbit approaches target weight, your vet will usually step the richer feeding back down gradually toward a normal adult pattern: unlimited hay, measured standard pellets, and daily greens. Sudden stops and starts both risk gut trouble, so taper over days. Keep weighing fortnightly for a while after you reach target, because a second slide is easiest to catch in its first small drop.
Gentle exercise in a safe pen supports appetite and muscle rebuilding better than constant confinement, provided your vet is happy for activity at this stage. Keep sessions calm and short at first for a rabbit still regaining strength.
