1) One is only allowed to exert oneself on Shabbat in order to alleviate an animal's suffering, but not to provide it with additional comforts or pleasure (Mishna Berurah O''H 332:4).

1) Vetches are species of flowering plants which are legume based. They were cultivated from very early days as food crops. 2) The Sages forbade using of certain remedies on Shabbat, however, the prohibition doesn't apply to animals (Mishna Berurah 332:5). 3) The Mishna Berurah (332:6) rules that a Gentile may be used even if there is no danger to an animals life, as long as it's suffering in some way.

1) The word ''muktzeh'' literally means ''set apart'', when applied to Shabbat, this term refers to items which, due to a rabbinical decree, one may not move. Two main reasons have been suggested to explain why such a decree was necessary: a) As a safeguard against the performance of a Biblical prohibition; in other words, if moving a pen is prohibited, then the probability of one accidently writing on Shabbat is greatly minimized; b) In order to differentiate Shabbat from a regular weekday. Limiting the items one can move on Shabbat, limits the amount of ''weekday'' activity that one can be involved in. The following are not ''muktzeh'' and so can be moved on Shabbat. 2) Without being ritually slaughtered (''shechita''). 3) Some authorities say that where the animal was in good health before Shabbat and then died unexpectedly on Shabbat, it is ''muktzeh'' (See Shulchan Aruch 324:7). 4) Some authorities say that if the broken item is no longer fit for its original use, it is ''muktzeh'', even though it is fit for a different use. This aspect of the ''muktzeh'' prohibition is called ''nolad'', which literally means ''came into existence''. There are two types of ''nolad'': a) Items that were not in existence at all before Shabbat or Yom Tov, for example, newly laid eggs. All items in this category are ''muktzeh''; b) Items that were in existence before Shabbat, but changed and assumed a new form on Shabbat; most items in this category are not considered ''muktzeh''. 5) Or other animals. 6) But they are all ''muktzeh'' on Yom Tov. In general, the ''muktzeh'' prohibition is more stringent on Yom Tov (Mishna Berurah 495:17). 7) That have been put out to dry, and one wouldn't use them until the drying process is complete. Additionally, during one stage in the process, they are repulsive and unfit for eating. These two factors render them ''muktzeh'' (Shulchan Aruch 310:2).
