So my kitties have been wanting to go outside, Ive got a screened in porch but Im not sure that they couldnt escape (just moved in) so Im not letting them out there yet. I measured Kinky and Nermal right behind the shoulders and theyre 19 & 20 inches. The only cat harnesses I can find are 14" or 16". I know my cats arent the only big kitties (and theyre not really fat, just big!) so where do you find accessories for them?
