Najis

In Islamic law, najis (Arabic: نجس‎) means ritually unclean. According to Islam, there are two kinds of najis: the essential najis which cannot be cleaned and the unessential najis which become najis while in contact with another najis. Contact with najis things brings a Muslim into a state of ritual impurity (Arabic: نجاسة‎ najāsa, in opposition to ṭahārah, ritual purity). Ritual purification is then required before religious duties such as regular prayers are performed.

I bought a cat recently and didn’t know the previous owners were feeding him food that contained pork. Does that fact make the bowl or glass used by me to feed the cat Najis? Do I have to get rid of the cat even if I don't feed it pork? Sayyed Mohammad Al-Musawi	I understand that the type of alcohol used in hand gel and wipes is different from the alcohol that intoxicates, but are we allowed to use such alcohol gel and wipes and does that cause the hands to become Najis?
