The short answer for a fast-habituating breed
Rotate a Devon Rex's toys every two to three days. Few breeds lose interest faster: a Devon Rex investigates a new object completely, learns its every move and sound, and is then ready for the next puzzle, so a toy left out permanently becomes furniture within the week. Work with a small active set of three or four toys at a time, then exchange most of that set for toys that have been hidden away resting. Rest is the mechanism that makes rotation work, because several days out of sight restore novelty almost as effectively as a new purchase. Keep one beloved constant, often a particular soft toy he carries or sleeps with, permanently available, since rotation should refresh his world, not confiscate his security object.
Build a rotation that fits how a Devon Rex plays
A Devon Rex plays socially, acrobatically, and with his mouth, so curate the resting box by type rather than by count. Hold back a mix: a wand toy for interactive hunting, balls of different weights and sounds for solo batting, a kicker toy for wrestling, a crinkle or texture toy, and one puzzle or treat-dispensing option. Each swap should change the character of the offering, not just its colour, so exchange the wand and kicker one round, the balls and puzzle the next. Devon Rexes are heat-seekers with fine coats, and toys left in a sunny window spot or near his warm perch get investigated sooner. Supervise anything with string, feathers, or glued parts, and store interactive wands away between sessions both for safety and because absence keeps them thrilling.
Signs the current rotation is too slow or too fast
Your Devon Rex grades the schedule for you. Toys ignored within a day, a cat drifting back to cupboards, shoulders, and midnight mischief, or play sessions that start flat all say the rotation is too slow or the rested toys have not rested long enough; shorten the cycle to every other day or enlarge the resting pool. The opposite error exists too. A Devon Rex who seems unsettled, checks the toy corner repeatedly, or carries one toy everywhere may be missing a favourite that was rotated away, so return it and rotate around it. Frayed fabric, loose eyes, cracked plastic, or a bell escaping its casing means retirement, not rotation, and a Rex who chews toys apart needs sturdier replacements rather than repaired ones. Adjust one variable at a time so you can tell what worked.
Make rested toys feel genuinely new
Reintroduction technique matters as much as timing. Do not simply scatter the rested set on the floor in the morning; bring one toy back inside an interactive session, dragging the wand from behind furniture or rolling the ball past his perch so he discovers it in motion. A paper bag or box placed with a rested toy inside adds a layer of investigation a Devon Rex relishes. Scent helps too: a toy stored in a drawer with a worn household t-shirt returns smelling interestingly of his people. Rotate the environment occasionally alongside the toys, moving the cat tree to a different window or adding a tunnel for a few days, because a familiar toy in a new location is effectively a new game.
Put the rotation on the household calendar
Toy rotation fails quietly: everyone assumes someone else swapped the set, and the Devon Rex announces the oversight at midnight. Treat rotation like feeding, a small scheduled task with an owner. Note which set is out, which day it changes, and any toy retired or needing replacement, in the household's shared care plan. A sitter during a holiday week should inherit the rotation intact, since a Rex left with static toys and absent people will redecorate. KinsLe helps households stay consistent through Care Teams, where the toy swap for your Devon Rex can be assigned, dated, and marked completed, keeping his entertainment on schedule whoever is home.
