Puzzle 036: Feeding Time

ナゾ０３６　エサの時間
庭の檻でペットを飼っている人がいる。
毎日他の誰にもさわらせないほど
かわいがっているが、エサの時間に
なると２階へ言ったきり、なかなか
降りてこない。エサやりを誰がに
頼んでいるわけでもなく、２階から
エサを投げ出すこともしていない。
さて、この人のペットとはなんだろう？
カタカナ３文字で答えてね。

Google Translate
Some people keep pets in a cage in the garden. Ramo Sawa is not a pet to anyone other than daily, and said it is time for cutting the food into two floors, there is no hard exit. It's not even a spear who are asking the food, the two can not throw out the food from the floor. Well, this person will be allowed and what? I answered in three katakana characters.

Notes on Puzzle
This puzzle describes the feeding schedule of this one person and their pet: every day the person climbs up to the 2nd floor in order to feed the pet. The person is not dropping or throwing the food. What kind of pet needs its owner to go to the 2nd floor just to feed it? The answer uses 3 katakana. My dictionary gave 2 3-katakana possibilities for this animal. To my chagrin, I chose the wrong one to answer the first time. Oh well.
