ANSWERS

1. a. Trapping - Tzeida: Totally limiting the movement of a free animal in order to have the animal.

b. Slaughtering - Shochet: Removing the life of a living being (including any blood).

c. Skinning - Mafshit: Av: Skinning an animal in order to have the skin.

d. Tanning - M'abeid: Using a substance to physically change an object, to make it [more] usable.

e. Smoothing - M'machek: Thinning out a solid or semi-solid by way of scraping or smoothing.

f. Scratching out - M'sartet: Marking a material to facilitate folding, cutting or writing.

g. Cutting - M'chateich: Making anything usable by cutting it to a specific size.

2. In a case where the cat could have been caught easily already (e.g. with your own house-cat), it is considered "trapped" and one may close the door.

If however, it is a street cat which is loose and wild, locking him in a small garbage room in which he can be easily caught is forbidden. This is even forbidden if it is not one's intention and one doesn't benefit from the cat being trapped.

3. a. If it hurts a lot, and one only opens up the wound to let the pus go out.

b. If additional pus or blood is extracted by pressing, or a hole which can heal the wound is created.

4. - By dipping each piece in the salt one by one, right before it is eaten.
- By first adding oil or salad dressing and then salting it.

5. Only in small quantities in a non-concentrated form, because otherwise this is preparing a method to pickle or preserve food. This falls under the Melacha of M'abeid.

6. Because one is thinning out a semi-solid, which is Assur under the Melacha of M'macheik.

7. Yes, but only if one does it for the folding sake and not to "create" a fold with it for some purpose.

8. No, because this is cutting it to the wanted size, which is Chayav under the Melacha of M'chateich.
