Comfy Collars are used as an alternative to the traditional lampshade collar, to reduce the stress suffered by cats and dogs that are recovering from surgery or minor injuries. The comfy collar does not restrict the field of view, so your dog or cat is less likely to bash into furniture. It is also very easy for them to see and reach their food bowl. Each comfy collar has an outer layer and a separate inflatable inner tube, with a velcro fastening strap on the outside edge and fabric hoops to secure against your pet's collar on the inside edge. The top-up valve can be accessed through the outer layer and pushed in so that it stays flush. There is also a zip on the outer layer for easy removal of the inner tube. It is available in X - Small 17-22cm, Small 22-30cm, Medium 30-40cm and Large 42-55cm.
