I feel your loss Atrocities.
I also had something bad happening to me regarding pets.
A coworker's cat had produced offspring. Yeeha, kittens for me, i shouted
My girlfriend (now my wife) wanted cats too so we went over to his house to pick 2 kittens.
After a year, i suddenly could breath. This happened at 4 am and i was scared like hell. I got a puffer (don't know if this is the correct word, it's such an inhaling thingie) for my lungs and it was a bit better but not much. They tested my blood and i suddenly was allergic to cats. My whole life I had cats and now i can't even touch them or bingo. I like all pets but cats have such funny personalities.
Nobody we knew and trusted wanted to take our 2 cats so we had to do them to an animal shelter.
That hurts like hell especially since the people over there don't believe you since a lot of people lie to them and say they are allergic.
To this day my wife and i wonder how they are. Luckily after 2 weeks they where both adopted.
