| Abstract | A method for inducing cats to exercise consists of directing a beam of
invisible light produced by a hand-held laser apparatus onto the floor or
wall or other opaque surface in the vicinity of the cat, then moving the
laser so as to cause the bright pattern of light to move in an irregular
way fascinating to cats, and to any other animal with a chase instinct. |

Claims  |
|
|
What is claimed is:
1. A method of inducing aerobic exercise in an unrestrained cat comprising
the steps of:
(a) directing an intense coherent beam of invisible light produced by a
hand-held laser apparatus to produce a bright highly-focused pattern of
light at the intersection of the beam and an opaque surface, said pattern
being of visual interest to a cat; and
(b) selectively redirecting said beam out of the cat's immediate reach to
induce said cat to run and chase said beam and pattern of light around an
exercise area.
2. The method of claim 1 wherein said bright pattern of light is small in
area relative to a paw of the cat.
3. The method of claim 1 wherein said beam remains invisible between said
laser and said opaque surface until impinging on said opaque surface.
4. The method of claim 1 wherein step (b) includes sweeping said beam at an
angular speed to cause said pattern to move along said opaque surface at a
speed in the range of five to twenty-five feet per second. |

BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates to recreational and amusement devices for
domestic animals and, more particularly, to a method for exercising and
entertaining cats.
2. Discussion of the Prior Art
Cats are not characteristically disposed toward voluntary aerobic exercise.
It becomes the burden of the cat owner to create situations of sufficient
interest to the feline to induce even short-lived and modest exertion for
the health and well-being of the pet. Cats are, however, fascinated by
light and enthralled by unpredictable jumpy movements, as for instance, by
the bobbing end of a piece of hand-held string or yarn, or a ball rolling
and bouncing across a floor. Intense sunlight reflected from a mirror or
focused through a prism, if the room is sufficiently dark, will, when
moved irregularly, cause even the more sedentary of cats to scamper after
the lighted image in an amusing and therapeutic game of "cat and mouse."
The disruption of having to darken a room to stage a cat workout and the
uncertainty of collecting a convenient sunbeam in a lens or mirror render
these approaches to establishing a regular life-enhancing cat exercise
routine inconvenient at best.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide an
improved method of exercising a cat in normal day and night lighting
environments.
It is a further object of the present invention to provide a method of
providing amusing, entertaining and healthy exercise for a cat.
It is yet another object of the present invention to teach a method of
exercising a cat effortlessly at any time.
In accordance with the present invention, a light amplification by
stimulated emission of radiation (laser) device in a small hand-held
configuration is used to project and move a bright pattern of light around
a room to amuse and exercise a cat.
The method is effective, simple, convenient and inexpensive to practice and
provides healthy exercise for the cat and amusement and entertainment for
both the cat and the owner.
These and other objects, features and advantages of the present invention
will become apparent from the following description and accompanying
drawings of one specific embodiment thereof.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of a cat owner exercising a cat in accordance
with the present invention.
FIG. 2 is a plan view of a hand-held laser exerciser.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings, a light amplification by stimulated emission of
radiation (laser) apparatus 10 for exercising cats, in the hands of a cat
owner 12, emits an invisible beam 14 of light from and along the
longitudinal axis of the device barrel 16. Activation of the laser cat
exerciser 10 is controlled by spring-loaded trigger 18 energizing the
laser mechanism by completing a battery power circuit. A cat 20 reacts to
the bright pattern of light 22 occurring at the intersection of the laser
beam and an opaque surface, for example, the floor or wall of a room.
The involuntary and almost imperceptibly slight movements of the hand
holding the laser device of the present invention creates a jittery
animated effect in the light pattern at the opaque intersection appealing
to cats even when the device is held essentially steady.
Intentional movements of the hand-held cat exerciser cause angular changes
in the direction of the beam 14 and consequently the light pattern 22
moves unpredictably about the intersecting surfaces. The cat 20, intrigued
by the jumpy movement of the light pattern, experiences a playful and
healthy chase impulse and follows the irregularly moving light pattern
around the room to the cardio-vascular, respiratory, weight control, and
muscle tone benefit of the animal.
The coherent nature of a laser light beam results in a small intensely
bright pattern of light clearly visible in normal day light or artificial
night illumination, small enough relative to the paw of the cat to cause
interest without posing a threat, and sharply defined over long enough
distances (e.g., up to 150 feet) to provoke a full workout with long
sprints for the pet. Ideally the bright pattern of light is directed along
the floor, steps or wall at speeds sufficient to exert and entertain the
cat but not so discouragingly fast as to dissuade against the chase, i.e.,
typically in the general range of 5 to 25 feet per second. In other words,
the angular sweep speed of the laser beam is controlled by the cat owner
12 to effect an appropriate linear sweep speed of the pattern on the
opaque surface within the stated general range. It is understood, of
course, that the angular beam sweep speed required to effect a given
linear pattern speed depends upon the distance between the laser and the
surface on which the pattern impinges; specifically, as the distance
between the laser and the surface increases, the same linear pattern speed
is produced by a slower angular beam sweep speed. Release of trigger 18
interrupts the power circuit and extinguishes the laser beam, whereupon
the cat can return to more traditionally feline time passing until cat
owner 12 re-initiates the laser cat exerciser.
The light pattern projected by the laser cat exerciser is invisible until
intersection with an opaque surface. Lasers emitting various colors of
coherent light can be used and the laser apparatus can be distinctively
shaped and colored for easy identification.
Although particularly suited to amusing and exercising cats, the method of
the present invention can be applied to other domestic pets, for instance
dogs, ferrets, and any other animals with the chase instinct.
Inasmuch as the present invention is subject to many variations,
modifications and changes in detail, it is intended that the subject
matter discussed above and shown in the accompanying drawings be
interpreted as illustrative and not in a limiting sense.
