A woman's pet cat has grown so big it is the size of an adult male BOBCAT - and weighs in at 11kg.<br /><br />Dexter is a F6 savannah cat, which means he is six generations removed from a Serval, a wild cat native to Africa.<br /><br />Seven- year-old Dexter, weighs 24.3lbs, measures a whopping 89cm (35ins) and uses a 110L storage bin as a litter box. <br /><br />Dexter is so big he can only play with dog toys and eats dog treats. <br /><br />Owner Laura Kay, 34, was looking for an out-of-the-ordinary cat when she paid £1,900 for Dexter to a breeder in 2016. <br /><br />Laura, a laser technician from West Lincoln in Ontario, Canada, said: "I buy him dog toys because if I get him tiny little cat toys he'll just destroy them.<br /><br />"All cat towers are way too small for him. I bought him the biggest one he can find, but it's still way too small for him.<br /><br />"Cat treats are too small for him as well. If the ingredients are all the same, which they often are, I buy him dog treats".<br /><br />The most difficult thing to size up for Dexter was his litterbox, which Laura was never able to find. <br /><br />Instead she had to buy a huge 110L plastic crate.<br /><br />Laura said: "Litter boxes are all just way too small so I bought him a 30 gallon storage bin."<br /><br />The cat's size also sometimes strikes fear into bystanders during visits to the vet.<br /><br />Laura added: "The last time I've encountered somebody being afraid of him was at the vet. They were a bit worried about how he would react.<br /><br />"A cat his size could do a lot of damage. He has the strength to do it. He would never do something like that though."<br /><br />Dexter's size makes him an expensive pet to maintain. <br /><br />Laura spends about £90-a-month ($150 CAD) between toys, food and vet bills.<br /><br />Dexter is the apple of Laura's eye and she takes great care of him. <br /><br />She feeds him specially made meat mixes.<br /><br />She added: "He mostly eats raw ground chicken meat, specifically mixed for pet food.<br /><br />"If you were to try and make it yourself you would probably get the minerals and nutrients wrong. It's a special mix of parts."
