Mustafa is underweight, which is clear from pictures, but appears to be more injured emotionally by his unmerciful time in captivity.
"Mustafa is very shy," Creamer said. "He's really quite nervous and so we're just waiting for him to get a little bit more confident and not be afraid of us."
Though Hoover has perked up in the few days he's been with ADI, he appears to have lost a lot of weight quickly and is very tired and not eating well. Vets are concerned about parasites, but it's also possible he has broken teeth or a dental infection - all-too-common-problems in circus cats.
"Almost all of them, if they're of any age, have smashed teeth, because when people are handling animals in the circus, if they're causing any trouble, the first thing they do is smash them in the face with an iron bar," Creamer said. "The other thing is they chew the metal bars [of their cages] because they're desperate and they break their teeth."
