Animal blockage device

An animal blockage device for use with a support member which is to be protected from ascension by animals, comprising:

• an upper hollow casing and a lower hollow casing, said casings being rigid and having different respective opening to movably surround said support member, the opening of the upper casing being larger than the opening of the lower casing;
• first and second attachment members, said first attachment members movably attaching said upper casing directly or indirectly to said support member;
• the lower casing being movably attached by said second attachment members to said upper casing in such fashion that the top of the lower casing hangs from the upper casing via the second attachment members;
• wherein the first attachment members are spaced vertically from the second attachment members;
• wherein each of the upper and lower casings is laterally movable with respect to the support member when said support member is generally vertically oriented, so that when an animal seeking to ascend the support member encounters either said casing, the casing so encountered moves laterally to present an unstable surface;
• wherein said casings are tubes and each extend approximately 14 inches along the support member;
• wherein said support member is a pole having a diameter of approximately 1 inch;
• and
• wherein said upper casing has a diameter of approximately 33/8 inches and said lower casing has a diameter of approximately 21/2 inches.

An animal blockage device for a support member comprising:

• upper and lower casings each surrounding said support member, said upper casing having a larger width or lateral dimension than the width or lateral dimension of said lower casing;
• a first pair of chains for attaching said upper casing directly or indirectly to said support member;
• and
• a second pair of chains for attaching said upper casing to said lower casing such that a portion of said upper casing is attached to and overlaps said lower casing to provide an unstable surface.
