No need for another, regardless one pet can change a life, replacement will dig the hole deeper, even with good intentions it will hurt....
Sorry for going so deep it's 12 am for me XD
Humphrey had a wonderful life. I know what is feels like to lose pets and I know other people do too. It's going to be ok. You will make it through this.
Just because you don't care about anything or anyone isn't an excuse to be mean. This person just lost their hamster. This chat is to honor that hamster. If you are only here to be toxic. Take your negativity somewhere else.
No matter the variety of the animal, it's cruel to not care about a death. Have you considered that you may be psychotic? The lack of empathy is a common sign. Just saying!
