Today's example: Someone I know on Facebook (someone I went to school with years ago, rather than a friend per se) posted yesterday evening excitedly that she got a puppy yesterday. No word of a lie this morning she is advertising it for sale because it 'doesn't get on with the cat'. Would you not think about how a puppy and cat would mix before you got a puppy? And if they didn't get along wouldn't you put a bit of effort in giving them time to get used to each other, rather than just 1 night? The poor thing will probably end up at an animal shelter or similar, or sold to some random who may or may not take good care of it.
I also had a work colleague who got through about 3 dogs in one year by taking on each one and then getting rid of each of them for various reasons (too noisy, needs too much walking etc) apparently having learnt nothing from each experience that dogs are actually a big commitment and can be hard work, and that maybe she shouldn't be taking one on unless she can make it's needs.
It leaves me so angry and sad. All the local animal shelters around here are full of abandoned pets that people have lost interest in. AIBU to think that if you take on a pet that it should (unless in exceptional circumstances) be a commitment to look after that animal for all it's life, and that should put some thought beforehand into how you would cope if your circumstances change etc?
