With dh's work we move around every few years and its become apparent just what crappy pet owners people can be.
example, a lady put her elderly cat in a shelter because they wouldnt be able to afford cattery fees if they wanted to visit family... a few weeks later they purchase a very expensive kitten!
My neighbour spent £1000 (without telling his wife) on a dog only to rehome it again a few weeks later because he was off back to the uk for a fight (cage fighting, not a random fight) and his wife wanted to go with him and again they couldnt afford kennel fees.
Another couple have rehomed their dog after finding out the cost of shipping the dog back to the uk... it has been made blatantly clear to everyone here the costs involved.
A lady I know rehomed their dog as it started showing aggression towards children and she had just had a baby. Fine, children always come first but I think the fact that she shut the dog outside all day so she didnt have to deal with a dog and a child has something to do with his sudden aggression.
One of my friends got a dog to keep her company while her hubby was away then rehomed it saying she couldnt cope with a dog while she was on her own.... a week before her hubby was due back!
Alot of people are due to move from here soon so suddenly there are alot of dogs and cats up for rehoming because its just one more thing they will have to deal with. Disgusting and I think people should have to sign a register to keep pets so that if you rehome a pet for a crappy reason you shouldnt then be able to just go a buy another one because it suits them at that time!
