<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I'm considering making a cat ladder / elevator. (Here are some:<br>
<a href="http://catladder.blogspot.com" target="_blank">http://catladder.blogspot.com</a>)<br>
<br>
My constraints:<br>
* usable by my relatively stupid and large (~12 lb) Maine Coone ("Ki")<br>
* gets my cat between my bedroom window (~15 ft off ground) and either<br>
the ground below or the wooden fence nearby (~5 ft high, ~8 ft away<br>
from the window wall)<br>
* can't require penetrating walls (against lease)<br>
* doesn't require me to frob it<br>
* safe for my cat<br>
* cheap and easy to make<br>
<br>
I've considered basically a few options:<br>
<br>
1. simple canvas ramp or tube, hooked to my window and the fence<br>
2. ditto, longer, staked into the ground (and parallel the wall)<br>
3. vertical canvas tube w/ spiral ramp inside, hooked to window<br>
(somewhat like closet hanging racks)<br>
4. (geeky and maybe failure prone) basket "elevator" triggered by<br>
weight in basket after a short time delay (like automated version of<br>
this: <a href="http://www.youtube.com/watch?v=e_1FknihCNI" target="_blank">http://www.youtube.com/watch?v=e_1FknihCNI</a>)<br>
<br>
I'm hesitant to try a hard ramp 'cause it'll be a pain to make, and an<br>
open spiral staircase 'cause my cat really is quite stupid (and I<br>
don't know if my woodcrafting abilities are up to it). And I can't do<br>
the simple boards-in-wall stairs design 'cause I can't attach stuff to<br>
the wall (nor do I have a ladder).<br>
<br>
Ideas? Anyone done something similar before?<br>
