面对宠物衰老和离世的痛楚，生物技术公司正推出一系列新的解决方案。Loyal公司正在测试三种潜在的犬类延寿药物，这项试验涉及约1,300只美国宠物犬1。与此同时，Viagen Pets提供猫狗克隆服务，单次克隆费用为5万美元1。Alcor冷冻保存设施则为宠物提供永久保存选项，目前已储存数百只宠物遗体1，最近更宣布完成了首次糖袋鼠的冷冻保存1。
科罗拉多州立大学临床科学教授洛里·科根表示，如果克隆宠物能为主人带来心灵平静，"我们有什么权利评判呢"1。这些选项反映出宠物主人与家庭成员动物之间的深厚情感纽带，以及生物技术在满足这种情感需求中的不断扩展角色。
Biotechnology firms are developing an expanding array of options for pet owners seeking to prolong their animals' lifespans or preserve them indefinitely. Loyal is currently testing three potential life-extension drugs for dogs, with trials involving approximately 1,300 American canines 1. Viagen Pets offers cloning services for cats and dogs at a cost of $50,000 per animal 1, while Alcor, a cryopreservation facility, has stored the remains of hundreds of pets along with human bodies 1. The company recently announced its first cryopreservation of a sugar glider 1.
These emerging technologies raise ethical considerations about grief, attachment, and the limits of human intervention in pet care. Lori Kogan, a clinical sciences professor at Colorado State University, offered a perspective on the moral dimensions of pet cloning, stating that if cloning a pet can provide an owner with peace of mind, "what right do we have to judge?" 1
