Depends on the pets. Studies have shown that cats and dogs can tell stress levels or if someone is going to die. However, cats act more on those instincts than dogs do.
If you want an animal that will help you relax more, get a cat. Individuals who have cats calm themselves by petting or cuddling with them. They feel less lonely, more needed, and have less stress.
Note: This is only if you have one or two cats. Any number above four causes stress.

A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
