I'm very sorry you lost your dear Kitty to cancer. I can relate. I had to let my precious kitty Taco "go" on Feb 10. He'd been battling recurring fibrosarcoma since September (2 previous lump removal surgeries were unsuccessful). His scruff tumors had gotten to the point where they were protruding through his skin and were draining fluid and blood and for the last 2 days of his life he finally started to appear uncomfortable so I just had to make the choice. I'd had him for nearly 16 yrs, from the time he was 8 wks old. He'd been with me through a marriage, divorce, thick and thin. On Feb 14 I checked out the local Human Society website and saw a pic of a dear orange male (so was Taco, orange), only a year old. I adopted him that day and he's been a real hoot. he's surely not a replacement of Taco, could never be.........but he's been a welcome 'distraction' for me.........as Taco's passing was very difficult. The new guy, Hobee, he's so full of spunk and friskiness, always clowning around.
Also, I feared that Taco's little buddy "Cleo" would be very lost without him; you see, they had been inseparable for years; always sleeping together, snuggled up. where you'd find one, you'd find the other. She's about 13 yrs herself. I feared she'd be very lonely without him as she's never really been too close to my other 3 females. I got Hobee hoping she'd "adopt" him and they'd be new buddies. It's funny; she took to him immediately....very fascinated by him, always following him around........and lately I'll see her rub up against him, all friendly like, just the way she did with Taco (he doesn't see to care but she likes him!) She's never really been very social with my other females; a little standoffish or a bit of a sh*t disturber (LOL)...but she loved Taco and now really likes Hobee so she must have a thing for males, or maybe orange males?
It made me feel real good to 'save a life'. So whenever you feel ready, go for it.
