I went on vacation for about that long and had someone come in to check on bunny 2x day. He gets a small bowl of pellets a day, eat at will and still eats hay. Pet sitter would give him greens once a day. I would be concerned about the cats. Animals act different when owners are gone, why take a chance? I also bought a pet camera and was the best investment and peace of mind! I could check on him while I was out of the country. The best idea ever! I got the YI, simple to use! I also got magnetic calendar on the fridge door with all instructions and things to watch out for, like small poops and chewed furniture or mats or whatever.
