Shorter Bouts Replace the Long Roam
Exercise needs change for a senior Californian rabbit first in rhythm rather than in kind. She still needs daily time out of her pen to keep her gut moving, her muscles working, and her mind occupied, but the long, continuous roaming of a young Californian gives way to movement in instalments: a deliberate tour of her space, a rest in a favourite spot, then another tour. Build her routine around several shorter sessions across her active periods instead of one marathon, and let her set the transitions. A senior Californian who is repeatedly picked up and relocated to encourage more exercise usually responds by moving less, because the outing stops feeling like hers.
A Big Rabbit's Weight Changes the Terrain Rules
The Californian is one of the larger rabbit breeds, and a senior Californian carries that substantial frame on ageing hocks and joints. Terrain therefore becomes an exercise decision in itself. She should be moving on grass, soil, low-pile carpet, or matting that gives her feet grip and some give, never on polished floors where her hind feet skid outward and strain her hips. Sore hocks are a standing risk in heavy rabbits, and exercise on hard or abrasive ground worsens them, so inspect the fur and skin on her hind feet regularly and treat redness as a reason to soften her surfaces immediately. Gentle slopes are fine and even useful, but remove anything she must jump down from, because landing loads a big rabbit's front legs and spine hard.
Weight and Movement Now Police Each Other
For a senior Californian rabbit, exercise and weight form a loop that needs watching from both ends. As she moves less, she gains weight more easily, and every extra pound makes moving less comfortable, which reduces movement further. Her daily hay should remain the bulk of what she eats during and after exercise time, with pellets and treats measured rather than scattered freely, so activity is not quietly outpaced by intake. Scatter her greens along her exercise route so walking is rewarded with forage instead of calories delivered in a bowl. Weigh her regularly and honestly; hands on a large rabbit can be fooled by her own substantial build, and a steady upward trend is a signal to adjust food and gently increase session frequency rather than session length.
Protect the Active Hours and the Rest Between
A senior Californian rabbit still keeps crepuscular habits, most willing to move in the morning and evening, and her exercise plan works best when it follows that pattern rather than the household's convenience. In warm weather those cooler hours matter doubly for a big rabbit, who sheds heat poorly and will choose inactivity, sometimes dangerously, over moving in the heat. Between sessions, her rest should be genuinely restful: a quiet, shaded, draught-free corner with deep bedding where she can stretch her full length. Rest is not the absence of exercise in a senior's programme; it is when muscles recover, and a Californian who is disturbed constantly through the day will have less to give her evening session.
Movement Changes That Mean a Vet Visit
Contact a rabbit-savvy vet if a senior Californian's exercise tolerance drops suddenly rather than gradually, if she stops coming out for sessions she used to take, or if she moves with a new limp, dragging toe, or reluctance to put weight through a hind leg. A heavy rabbit who cannot clean her rear, whose droppings shrink or dwindle, or who sits hunched pressing her belly to the ground needs assessment promptly, because appetite and gut movement in rabbits are not things to monitor for days. Bringing her weight history, session notes, and hock checks from KinsLe's Pet Passport lets the vet separate a big rabbit's normal ageing from a change that needs treatment.
