Cat food containing pork

Q: We have a couple of cats at home and rely on buying brand cat jelly and dry food. I usually buy fish selection but recently discovered that both of the fish selection cat food brands have traces of pork in the food. It would be difficult to have to make homemade meat for them every day because we have many cats and they eat multiple times a day. Its a must to feed cats meat because otherwise they’ll be unhealthy. So what shall I do? I'm afraid they’ll get sick of eating tuna all the time and they need a lot of nutrition which can be found in these brand foods.

Feeling despondent

Q: What is the reason if we desperately pray a lot for a job or something else and when we finally get it, its bad/unenjoyable? Do we have to think that maybe this happened because Allah is testing us? Or are we being punished?

Can you help me figure out how to perceive Allah when I’m struggling? Like if I’m praying for a job opportunity, or something else, and nothing is going my way?

I know I have to remember that Allah is the Provider of Rizq and that He always wants the best for us. But what if I don’t know if what I’m receiving (rejections/sadness) is due to a trial or if its a punishment?
