Because unlike the law in the US, the legal stance on leaving money to your animal is very different here. "So, in legal terms, a cat, a dog or tortoise is a chattel and not a legal person. In the same way as you can’t leave money in your will to other chattels - for example your favourite Xbox or fridge - you can’t leave money to your pet". This is generally a good solution but there is no legal onus on the recipient to keep the pet. The Pet Trust usually appoints two people to be the trustees of a trust which has in it (a) the pet and (b) some funds to cover the maintenance costs of the pet.
